The successful test of concept shows that the novel design, using a high-temperature superconductor, could help power tomorrow's particle accelerators, fusion machines and research magnets.
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.
Emergence of unusual metallic state supports role of "charge stripes" in formation of charge-carrier pairs essential to resistance-free flow of electrical current.
The compact coil could lead to a new generation of magnets for biomedical research, nuclear fusion reactors and many applications in between.
In a hydrogen-packed compound squeezed to ultra-high pressures, scientists have observed electrical current with zero resistance tantalizingly close to room temperature.
Scientists have long pursued the goal of superconductivity at room temperature. This work opens a route towards one day stabilizing superconductivity at room temperature, which could open tremendous technological opportunities.
With funding from the National Science Foundation, scientists and engineers will determine the best way to build a new class of record-breaking instruments.
MagLab experts fine-tuned a furnace for pressure-cooking a novel superconducting magnet. Now they're about to build its big brother.
A material already known for its unique behavior is found to carry current in a way never before observed.
"GAP" award will help further breakthrough treatment system for next-generation superconducting magnets.
