Scientists from the Max Planck Institute for Solid State Research, led by Minu Kim, the leader of the high-pressure synthesis group in the Department of Quantum Materials (Takagi), announced their discovery of superconductivity in new perovskite antimonates, Ba1-xKxSbO3 (BKSO), in collaboration with University of British Columbia (Canada), ISIS facility (U.K.), Canadian Light Source (Canada), University of Saskatchewan (Canada) and The University of Tokyo (Japan). The discovery allowed the team, via a comparative study of the electronic phase diagram with sibling compounds, Ba1-xKxBiO3, to address long-standing questions on the mechanism of high transition temperature, Tc, in a class of perovskite superconductors.
