Rational Design and Discovery of Novel High Temperature Superconductors

Rational design of high temperature superconductors, (HTSCs), with predicted stoichiometry and transition temperature, Tc, is a major challenge in superconductivity. We presented in previous APS meetings (2015, 2016, 2017 and 2018), our computational design model called Material Specific Characterization Dataset (MSCD) Framework, and also design algorithms, and generalized periodic system (GPS),for superconductors. Over the past year, we have put to experimental test, our designs of oxide, oxy-sulfide and oxy-chloride systems predicted by MSCD Framework to be HTSCs. At this March 2019 meeting, we present the experimental results of this great challenge and announce the discovery, at ambient pressure of new classes of HTSCs without copper.
