superconductor with Perovskite-type crystal structure Note 1 to entry: Perovskite-type structure has typical compositional and structural blocks of ABO3, where A and B refer to metallic elements and O is oxygen. Note 2 to entry: Perovskite superconductor includes Ba (Pb1−xBix) O3 and (Ba1−x Mx) BiO3 (where M = K, Rb).
