Abstract

Binary oxides with the stoichiometry ABO3 often have the perovskite structure. A large family of these oxides shows colossal magnetoresistance (CMR). In the case of the classical perovskite-related cuprate structure of YBa2Cu3O7-d (YBCO), superconductivity sets in under about 90 K, and further combining the perovskite lattice with inserted atomic layers, the critical temperature could be pushed up to 160 K. Mössbauer spectroscopy of these systems is rather challenging. The comparison of emission and transmission results can be very beneficial. This chapter focuses on the application of Mössbauer spectroscopy on perovskite-related systems where emission Mössbauer spectroscopy had a special contribution in exploring the structure and electronic or magnetic behavior of these materials. The discovery of high-Tc superconductivity by Bednorz and Möller in 1986 generated an almost unprecedented rush in science to solve the mechanism. Strontium ferrate (SrFeO3) has the classic perovskite structure just like lanthanum cobaltate (LaCoO3).
