Abstract

By utilizing multi-frequency electron paramagnetic resonance (EPR) spectroscopy, the manganese functional-centre site in manganese-modified polycrystalline lead titanate (PbTiO 3 ) was studied. Isovalent Mn 4+ ions were identified as substituting for Ti 4+ at the B-site of the perovskite ABO 3 lattice. Based on Newman superposition-model calculations, it could be shown that the value of the experimentally obtained fine-structure (FS) parameter B 2 0 is only consistent with a microstructure in which the Mn x Ti functional center follows the Ti x Ti cooperative displacement in the ferroelectric phase.
