Analysis of point defects in polycrystalline BaTiO3 by electron paramagnetic resonance
Abstract
Several paramagnetic point defects in BaTiO3 polycrystals were detected and identified using the electron paramagnetic resonance technique. Polycrystalline samples sintered in a reducing atmosphere showed a broad signal with a giromagnetic constant of 1.932. This signal, observed only in conducting ceramics, was assigned to Ti3+ and its related complexes. VBa and VTi defects were found at giromagetic constants of 1.974 and 2.004, respectively. …
