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.
MagLab-industry partnership ups the critical current density of this high-temperature superconductor by a third.
This finding sheds light on the role of quasiparticle mass enhancement near a quantum critical point in one of the leading families of high-temperature superconductors.
