Abstract

Using the self-consistent field multiple-scattering Xα method, we calculate and discuss the 3d energy levels, which are potentially photorefractively active for substitutional iron, chromium, and manganese ions in BaTiO₃ relative to the valence band edge. Moreover, we examine the almost intrinsic defect formed by an oxygen vacancy associated with titanium.
