Sažetak
The intrinsic iron(III) impurity center in polycrystalline lead titanate was investigated by means of high-frequency electron paramagnetic resonance spectroscopy in order to determine the local-environment sensitive fine-structure parameter D. At a spectrometer frequency of 190 GHz, a spectral analysis of a powder sample was unambiguously possible. The observed mean value D=+35.28 GHz can be rationalized if Fe3+ ions substitute for Ti4+ at the B site of the perovskite ABO(3) lattice forming a directly coordinated Fe-Ti'-V-O(++) defect associate. A consistent fit of the multifrequency data necessitated the use of a distribution of the D values with a variance of about 1 GHz. This statistical distribution of values is probably related to more distant defects and vacancies.
