Superconductivity in new complex intermetallics

ORAL

Abstract

In this talk I will breifly describe our recent results on the discovery of superconductivity at temperatures between 2 and 8 K in several previously unreported ternary compounds based on Ta. One of the new materials, based on Ta and a late transition metal, is a noncentrosymmetric chiral superconductor with a HC2(0) that appears to exceed the Pauli limit. If time permits I will also describe our results on a new high entropy alloy superconductor. We have collaborated with many others to complete this work.
