Correlation between superconducting transition temperatures and physical properties

ORAL

Abstract

We analyze the correlation between the superconducting transition temperatures and the physical properties in the normal state, extending the previous work by Hirsch[1]. Several classes of superconductors, including the elemental superconductors, the A15 compounds and the hydrides etc, are studied and analyzed. We identify the properties that correlate with Tc in each class of superconductors. In particular, the correlation between the metallic covalent bonding and the superconducting transition temperatures is strong, which suggests a possible route for finding new high temperature superconductors by high throughput search for compounds with strong metallic covalent bonds.
