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.
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.
Missing your sports? Fear not, nerds of the world. We invented a few geeky ones to tide you over.
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.
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.
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.
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.
A team tackling some gnarly physics using tricky techniques rounds a critical corner. Joy ensues. Then, back to work.
Researchers put little permanent magnets into large electromagnets to find out how to make them better.
High magnetic fields usually kill superconductivity. But in this material, it brought it back to life.
