Abstract

Optical excitation of trivalent platinum (5d ⁷ , t ⁶ e) ions in lead titanate single crystals have been observed for the first time by electron paramagnetic resonance (EPR). The g and hyperfine coupling A tensors were found to be axial: g _∥ =1.938, g _⊥ =2.478, A _∥ =0.0164 cm ^-1 , and A _⊥ =0.0324 cm ^-1 . Analysis of the EPR spectra using crystal field theory indicates that the Pt ⁺³ ions are in tetragonally distorted (elongated) octahedral sites, strongly suggesting that they substitute for the central Ti ⁺⁴ ions in the perovskite lattice.
