Abstract: Here we investigated the doping mechanisms and electrical properties of Ba-substituted Bi3.36Mg1.92-xBaxNb2.72O14.36 (BMBN) pyrochlores. Phase-pure BMBN pyrochlores prepared by solid-state reaction were found to crystallise in a cubic structure (Fd3m; No. 227) with their lattice… read more here.
