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.

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.
