Abstract
The oxidation states of Mn in Mn-doped BaTiO3 were investigated by ESR, supplemented by thermal analysis and electrical conductivity data. Direct evidence for the presence of Mn2+ and Mn4+ and indirect evidence for the presence of Mn3+ is presented. Based on the Jahn-Teller distortion characteristics of the various oxidation states of Mn, presence of Mn3+ has been shown to stabilize the tetragonal (and orthorhombic) phases while Mn2+ and Mn4+ favor the cubic phase. These results clarify the conditions necessary for the production of high resistivity Mn-doped BaTiO3 ceramics.
