Electronic and ionic transport properties and other physical aspects of perovskites
TL;DR: The perovskites and their related structures exhibit several features of technical as well as fundamental interest, such as oxide-ion conduction with/without electronic conduction, oxidation catalysis, ferroic displacements in classic and relaxor ferroelectrics, half-metallic ferromagnetism and high-temperature superconductivity.
