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.
Recent measurements of superconducting tapes in the MagLab's 45-tesla hybrid magnet shows that the power function dependence of current on magnetic field remains valid up to 45T in liquid helium, while for magnetic field in the plane of the tape conductor, almost no magnetic field dependence is observed. Thus design of ultra-high-field magnets capable of reaching 50T and higher is feasible using the latest high-critical current density REBCO tape.
