These monthly highlights, selected by MagLab Director Greg Boebinger, represent the most promising and cutting-edge research underway in the lab’s seven user facilities.
Electron spin resonance work shows how transition metal can retain quantum information, important work on the path to next-generation quantum technologies.
Little is known about the path of metabolic waste clearance from the brain. Here, high-field magnetic resonance images a possible pathway for metabolic waste removal from the brain and suggests that waste clearance may be one reason why we sleep.
A nematic phase is where the molecular/atomic dynamics show elements of both liquids and solids, like in liquid crystal displays on digital watches or calculators. Using high magnetic fields and high pressure, researchers probed the electronic states of an iron-based superconductor and found that its nematic state weakened superconductivity.
This finding demonstrates a path forward to dramatically enhance sensitivity for molecule concentration measurement by magnetic resonance using Overhauser DNP.

Studies of uranium ditelluride in high magnetic fields show superconductivity switching off at 35 T, but reoccurring at higher magnetic fields between 40 and 65 T.
Research on doped SrCu2(BO3)2 shows anomalies in the magnetization.
Small additions of elemental Hafnium boosts current-carrying capability in Nb3Sn superconductor.
In Sr3NiIrO6 vibrations in the crystal lattice (phonons) play an important role in its intriguing magnetic properties that result in a very high coercive field of 55 T. Using a combination of pulsed and DC magnetic fields coupled with magnetization and far-infrared spectroscopy, researchers were able to conclusively link the phonons to the magnetic behavior.

Study of helium atoms at low temperatures illuminate extreme quantum effects that were earlier predicted.
Very high magnetic fields now enable researchers to understand what surrounds calcium atoms in materials.
The findings contribute to scientists' understanding of magnetic materials that could point the way to future applications.
MagLab users have modified the critical current of Nb3SN, a material that was thought to be fully exploited, and boosted its performance by 50%.
The observation of topological states coupled with superconductivity represents an opportunity for scientists to manipulate nontrivial superconducting states via the spin-orbit interaction. While superconductivity has been extensively studied since its discovery in 1910, the advent of topological materials gives scientists a new avenue to explore quantum matter. BiPd is being studied using "MagLab-sized fields" by scientists from LSU in an effort to determine if it is indeed a topological superconductor.
To increase the rate of particle collisions in the Large Hadron Collider (LHC) at CERN, new powerful magnets will soon be made from Nb3Sn superconducting wires. Here, researchers report a change to the heat-treatment temperature to optimize Nb3Sn superconducting magnet performance.
Pulsed magnets are designed to operate near their structural limits to be able to generate extremely high magnetic fields. The coils have a limited life expectancy and thus need to be replaced on occasion. Fabrication of these large coils are now being done at the MagLab where advanced nondestructive examinations can be performed. Because of more rigorous quality controls and improvements in high-strength conductors and reinforcement materials, the lifetime of these coils can be extended.
With advanced techniques and world-record magnetic fields, researchers have detected new MRI signals from brain tumors.
Combining high-field NMR with infrared microscopy, scientists learned more about how gas diffuses in a novel class of molecular sieves that could one day be used for gas separation.
