Scientists have synthesized a new high-temperature superconductor

Phys.org  March 10, 2021
An international team of researchers (Russia, USA – University of Chicago, Spain, Italy, China)¬†performed theoretical and experimental research on yttrium hydride (YH6), one among the three highest-temperature superconductors known to date. All these hydrides reach their maximum superconductivity temperatures at very high pressures. The current challenge is to attain room-temperature superconductivity at lower pressures. In the case of YH6, the agreement between theory and experiment is rather poor. For example, the critical magnetic field observed in the experiment is 2 to 2.5 times greater as compared to theoretical predictions. This is the first-time scientists encounter such a discrepancy which is yet to be explained. Perhaps, some additional physical effects contribute to this material’s superconductivity and were not accounted for in theoretical calculations…read more. TECHNICAL ARTICLE
