Algorithms for Rational Design of Oxide High-Tc Superconductors without Copper*

The design and search for novel high-Tc superconductors is one of the major challenges of condensed matter Physics. Though serendipity and "enlightened empirical methods" have been key discovery strategies, we have developed a novel powerful rational design algorithm-based framework called MSCD (Material Specific Characterization Dataset), defined in APS March Meeting (2015 APS Abstract S25.00011). Again, in 2016 APS March Meeting, we used MSCD to design YBa2Cu3O7-Like high-Tc superconductors(2016 APS Abstract F8.005). Now we have expanded the design algorithms to include all families of oxide superconductors represented as MnOn and MnOn+1, where M = cations and O = oxide anion and n =1, 2. ...20. Here, we present these MSCD algorithms and examples of material specific designs of families of potential high-Tc oxide superconductors without copper, and their estimated transition temperatures,Tcs.
