|Smart Non-Linear Transport Technique Expands the Frontier of Superconductor Research||
Superconductors conduct large amounts of electricity without losses. They are also used to create very large magnetic fields, for example in MRI machines, to study materials and medicine. Here, researchers developed a fast, new "smart" technique to measure how much current a superconductor can carry using very high pulsed magnetic fields.
|Inducing Magnetic Ring Currents in Non-Magnetic Aromatic Molecules||
Magnetic induction is used in technology to convert an applied magnetic field into an electric current and vice versa. Nature also makes extensive use of this principle at the atomic and molecular level giving scientists a window to observe material properties. Using the 25 T Split-Helix magnet, researchers observed changes in the optical properties of organic materials due to currents induced by applied magnetic fields flowing in molecular rings, evidence that could increase the list of materials that could be used in future magnetic technologies.
|Integrated Coil Form Technology for Ultra High Magnetic Fields||
Tests of the first Integrated Coil Form test coil wound using REBCO superconducting tape show promise for use in ultra powerful magnets of the future.
|Magnetoelectric coupling at a transition between two spin states||
Materials with magnetoelectric coupling - a combination of magnetic and electric properties - have potential applications in low-power magnetic sensing, new computational devices and high-frequency electronics. Here, researchers find a new class of magnetoelectric materials controlled by spin state switching.
|Molecular magnetic building blocks||
This study reports the first transition metal compounds featuring mixed fluoride–cyanide ligands. A significant enhancement of the magnetic anisotropy, as compared to the pure fluoride ligated compounds, is demonstrated by combined analysis of high-field electron paramagnetic resonance (HF-EPR) spectroscopy and magnetization measurements.
|REBCO Fatigue testing shows promise for future magnets||
Tests of high-temperature superconducting REBCO tapes at 4.2 K showed resistance to cyclic loading, demonstrating that it is a promising material for designing HTS magnets of the future.
|Exploring topological semimetals in high magnetic fields||
Topological semimetals are an exciting new area of research due to their number of predicted and unexpected quantum mechanical states. Understanding these materials may also lead to quantum devices that function at near room temperature.
|Record-Breaking Magnetoresistance measured in Natural Graphite||
Researchers demonstrate a new record magnetoresistance in graphene by improving the contacting method, which helps improve our understanding of the material and can be useful in future sensors, compasses and other applications.
|Nuclear Spin Patterning Controls Electron Spin Coherence||
Electron spin resonance work shows how transition metal can retain quantum information, important work on the path to next-generation quantum technologies.
|Nematic Phase Weakens Superconductivity||
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.
