"A few days ago our paper on UO2 was accepted to be published in Nature Communications. Another paper, on UN, received a very good reviews and should be accepted to Nature Sci. Reports soon. All of this work would not be possible without support from the Pulsed Field Facility. I would like to take this opportunity to let you know that the MagLab user program, and especially its user support, is excellent. The help and technical support I received from Neil Harrison, Vivien Zapf and especially Marcelo Jaime were crucial to the success of the projects. Thank you for the opportunity to be a part of this successful program, and I'm looking forward to our future collaboration!"

"We wanted to thank you for the support that our group received during our magnetostriction and magnetization experiments at the Pulsed Field Facility on USb2. This experiment began in the summer of 2014 and resulted in the publication “Tricritical point of the f-electron antiferromagnet USb2 driven by high magnetic fields,” published in Physical Review B in January of 2017. This project not only produced a publication, but also contributed to the conversion of a postdoctoral researcher to a permanent staff position, established a collaboration between two Department of Energy Laboratories (Lawrence Livermore and Los Alamos), the NIST Center for Neutron Research and the University of Maryland, and introduced our graduate student, I-Lin Lui, to high-magnetic field research in support of her doctoral thesis work.

"This project used both the magnetostriction and magnetization capabilities at the PFF, and was therefore supported by Marcelo Jaime for the magnetostriction experiments, and Marcelo and Neil Harrison for the magnetization experiments. Both of these techniques were new to us, but Marcelo and Neil both did a great job of explaining the techniques and helping with the experimental difficulties inherent in both. In addition to the usual difficulties related to these PFF techniques, the radioactive properties of our materials (USb2 and UBi2) added another layer of complication in the shipping and handling aspects, which Marcelo helped to guide along as we navigated the samples from LLNL to LANL on multiple occasions.

"We look forward to the opportunity to do similar work at the PFF in the future."

"I had the opportunity to work with Dr. Fred Mentink on the ss MAS DNP instrument and I couldn't have asked for a more helpful and knowledgable person to work with on the instrument. Any time there was an issue he was always quick to troubleshoot and resolve the problem, getting us back on track as quickly as possible. He ensured that safe measures were taken and went above and beyond to help us get all the data we needed in our short trip. I hope to work with him again in the future for further DNP studies. I would also like to mention Dr. Zhehong Gan, Dr. Hans van Tol, and Dr. Thierry Dubroca who were all extremely helpful throughout the process.

"While there were many ups and downs (as to be expected when doing anything science related) I had a wonderful experience at the MagLab and hope to come back in the future. It is clear the employees at the MagLab truly love their jobs/workplace because I have yet to meet a person there who isn't extremely kind, helpful, and willing to go above and beyond.

"And finally, I love the ISM Safety measures that the MagLab uses and have started applying the same practices in my own lab since my first visit earlier this year."

"This is to acknowledge the tremendous expertise of and the help rendered by Dr. Marcelo Jaime in the magnetostriction experiments at high fields in single crystals of UPt3. Thanks to the Pulsed Field Facility at the MagLab, we have obtained some incredible quality data. Two publications as a result of these measurements are currently being prepared and MagLab support will be acknowledged."

"Last week I had 35 T magnet time in Cell 12, performing torque magnetometry in the 3He system.

"The experiments went smoothly and we had no problems with equipment. The control room staff were (as always) efficient, courteous and accommodating. When we found out that the hybrid was unexpectedly offline, we requested that our shift be moved forward a few hours. This request was accepted without fuss, for which we are very grateful. The cryogenic system and the experimental instrumentation worked well, which I assume is thanks to Scott Maier and the rest of the technical support team.

"We had very useful interactions with Stan Tozer, Audrey Grockowiak and William Coniglio. Our main support came from David Graf. Once again, he went beyond the call of duty to help us before, during and after the experiment. Many of my experiences of working with scientists at the NHMFL are such that they feel more like a collaboration than a user support service and this was definitely true for this visit: David was an essential part of the experimental team and we would not have been able to achieve nearly as much without his input. World-leading facilities can only really work if they have world-leading scientists to assist users and I have no doubt that David fits into that category.

"We had a busy and productive visit, but it was also enjoyable and, I think, inspiring for the graduate students. We took lots of lovely data. The analysis continues..."

"In the past week, I have measured the magnetic properties of the samples annealed in the lab, and some good results have been obtained. I believe they will be a part of a good paper. The facilities are wonderful. William Coniglio and Bobby Pullum gave me much help on the three-day experiments. On the first day, William came to the lab early to show me how to load the samples, use the temperature controller, and communicate with the staff in control room. The staff in control room always double-checked with me to confirm I was ready. Sometimes they come to the cell to discuss with me face to face. The safety is great."

"I had a great experience at the ICR Facility last week. Both my undergrad working with me and I felt very welcome and supported by Dr. Amy McKenna, who explained step by step what she was doing with our samples and processing the data. We were very satisfied with our experience, and I intend to request magnet time at the ICR Facility in the future."

"Our experiments had a very ambitious schedule. Yet with the help of our user support scientists Brad Ramshaw, Ross MacDonald, Fedor Balakirev and Mun Chan, as well as support by Jon Betts, we managed to bring all experiments to a success. We are very thankful for their fantastic work and anticipate multiple publications from these very productive runs.

"I would like to thank the whole MagLab team for their great support and effort to help our projects. Other laboratories have big magnets, too, but it is this high level of effort and expertise of the staff members that makes a huge difference in the outcome."

"First of all let me say that Likai Song and Johannes McKay were a pleasure with whom to work. They helped me understand the equipment and worked very hard to acquire the needed spectra. During my stay there we all had very good discussions regarding the experiments and science in general.

"Second, the experiments and equipment produced data that will be very important to my study, data that I could not have obtained anywhere else. We plan on publishing the results in the near future.

"Finally, the Maglab is an amazing facility. It is well run, well staffed and well equipped."

"Regarding my recent visit to Tallahassee to use the resistive magnets, I would like to say that not only was the trip very fruitful, it was also enjoyable. This was largely due to the excellent support we received. Working with Stan Tozer and the pressure team is always productive and enables experiments that are just not possible to do anywhere else. A lot of preparation was done by Audrey Grockowiak and David Graf in advance of our arrival, which was most welcome and is the reason the experiments worked from the outset. David was also extremely helpful during the run. His experience, willingness to solve problems and calm attitude is what made performing the measurements a pleasant rather than stressful experience.

"I would also particularly like to note the excellent help and support that was provided by William Coniglio, who set up the radio-frequency measurements and frequently stayed in the cell with us when the experiments were running, often till very late, giving us advice and the benefit of his expertise.

"On the facilities side, the magnet ran smoothly during our time and I would like to thank the control room staff, who were happy to accommodate us on the occasions the experiments overran. This was my first experience of the extended shifts and, while tiring, they enabled us to get plenty of data.

"In summary, the facilities are what I come to the MagLab for, but it is the friendly expertise and the collaborative nature of the user support that makes me very happy to do so."

"My compliments again for the quick and extremely short-notice manner in which the EMR group, and specifically Hans van Tol was able to accommodate the measurements last week. From the Maglab's side, everything worked flawlessly, I am amazed how well the new pEDMR sample holders work in the corrugated waveguide system. The PEDOT devices we had from Utah had issues (our fault!), so we didn't get the publishable data that we wanted. However, the time spent was nevertheless not wasted at all as we have gotten valuable information (tons of IV curves at many different magnetic fields and temperatures) on how to improve these samples for future measurement campaigns."

"I came to the MagLab to do a part of my PhD thesis at the NMR-MRI/S Facility and it actually lead to the best part of my thesis. It was not only because I was able to use the world's strongest MRI machine for my experiments. It was the support from the scientists that I was received there. All the equipment was working perfectly and everyone was really helpful. Another great experience was the atmosphere at the lab. Everyone is trying to push the limits and to improve things. I benefited a lot from the time at the MagLab and I hope it wasn't my last visit there."

"In my 20-year association with the MagLab, I have never experienced user support as good or as comprehensive as I received on this magnet run. To be fair, the circumstances are unique: I injured my shoulder and was not able to travel to the lab for this run. My collaborators, Drs. Ju-Hyun Park and Dave Graf, are doing the work for me. They sent me data daily and were very responsive to my questions, suggestions, and comments. The circumstances are unusual, but to say that they are both providing user support well above and beyond the usual (and "the usual" at the MagLab/Tallahassee is pretty darn good in my experience) does not do them justice. I am very grateful to both Dave and Ju-Hyun, and to the lab that lets them do what they do so very, very well."

“Our quantum oscillation experiments down to mK temperatures in SCM1 were very successful. I was astonished by the level of sensitivity we were able to achieve. The detection system worked so well that we could detect nV level changes in signal and temperature variations < 0.5mK. We benefitted enormously from excellent user support: Ju-Hyun Park is outstanding not just in his technical ability, but also in his enthusiasm and cheerfulness in making himself available to help at just about any time during the experiment. We were very impressed at his dedication to ensuring not just that the system was running smoothly, but that we received any specialized assistance we required for our specific experiment to work.”

"We are grateful to MagLab staff members for their help during our last visit. Per our request, your support scientists wrote a program automating our measurements and the magnet. With the program, we were able to take much larger amount of data, increasing resolution of our measurements. In addition, they advised to use a minimum number of the magnet power sources and water pumps, thus increasing the magnetic field stability and data precision during the measurement. Furthermore, the shop staff was very kind to promptly address all our requests."

“It is our first time doing experiment in SCM1 and we feel the facilities are very user friendly. The loading and unloading samples are fast and there are plenty of instruments that we can choose from to build up our measurement system. Due to these conveniences, we were able to do the experiment very efficiently. … Overall, this is a successful trip.”

“We had a great and extremely productive week while we were in Tallahassee. Our experiment went as smoothly as it could have thanks to the Millikelvin staff. They were always there to help us load our samples and prepare the probes that needed a bit of modification for our experiment. They were perfect. Furthermore, we had great interactions with other scientists there who were not even formally part of the experiment … who spoke with us about the theoretical implications and interpretations of our data. These discussions were invaluable. The trip to Tallahassee would have been worth it just to speak with them!”

“We had two very successful experiments at the MagLab, first on the 20T SC magnet to continue previous experiments on the 35T magnet up to higher pressure, and a second experiment on a different material again on the 35T. These pressure cells are fantastic and a game changer. Many thanks to your staff scientists for their superb help and support to my team during these experiments. … I run a lab with 13 neutron scattering and imaging instruments and about 400 experiments per year at the Swiss Spallation Neutron Source. I know how difficult it can be for staff to work under (user) pressure and the challenges of pressure work in general. I was very impressed by the MagLab and especially the commitment and dedication of the team. Superb job, thanks again!”

"I think the Magnet Lab is a great place to do research, not only because of its unique resources, but also because you can breathe science in the air! Everything is arranged so that you keep sharing your perspectives and projects with the staff scientists, the postdocs, the students and the visiting users. The lab environment encourages the interaction between all the members, which I think is crucial for scientific productivity."

"The experiment … is my first time to collaborate with NHFML researchers and get machine time to perform AC susceptibility measurements at ultra-low temperatures. In this program, everything was going on well and we have not met any problems. The experimental results are also perfect. We hope to be able to have more chance to perform nice measurements in NHMFL facilities."

"The technical and scientific support I received from Dmitry Smirnov, Jonathan Ludwig, and Jean-Marie Poumirol was exceptional. Everyone went above and beyond to help me complete all planned measurements with success. Even the more challenging requests (i.e. very low background at low wave numbers, requiring very precise alignment) were met with enthusiasm and unsurpassed dedication."

— Anjan Reijnders, University of Toronto

"We were very pleased with all aspects of the visit! The instrumentation we employed performed exceedingly well and the support scientists Drs. Zhehong Gan and Ivan Hung were both highly proficient and very pleasant to work with. We had no concerns with our visit and indeed hope to return for some follow-up experiments as our sample preparation proceeds."

"I was very impressed by the ability to generate 80 kHz (and potentially even higher) B1 fields with the newly-designed probe by Peter Gor'kov. This will be indispensable as we move to detecting the much larger CH couplings in doubly labeled oriented membrane proteins for their subsequent structure determination. Without any doubt, NHFML constitutes the forefront for such studies being at the cutting edge of the instrumentation and methodology development for biological solid-state NMR."
