Researchers from Tokyo Metropolitan University mixed and designed a new, high-entropy alloy (HEA) superconductor, using extensive data on simple superconducting substances with a specific crystal structure. HEAs are known to preserve superconducting characteristics up to extremely high pressures. The new superconductor, Co0.2Ni0.1Cu0.1Rh0.3Ir0.3Zr2, has a superconducting transition at 8K, a relatively high temperature for an HEA. The team's approach may be applied to discovering new superconducting materials with specific desirable properties.
