The displacements of Fe3+ (at the Ta5+ site) along the [001] direction in KTaO3 crystal, caused by the electric field, have been studied by calculating the electric-field-induced zero-field splittings from the microscopic mechanisms and the empirical superposition model. It is found that the Fe3+ displacements obtained by the two methods at the same electric-field strength and temperature are close to each other. These displacements are also close to that estimated from the force-balance equation. It is suggested that the electric-field-induced zero-field splitting can be attributed primarily to the above displacement and the temperature dependence of the electric-field-induced zero-field splitting is mainly due to the change in the dielectric constant of KTaO3 with temperature.

New Perturbation

The contributions to the zero-field splitting parameter D for an axial crystalline electric field for Mn2+ (site I) in La2Mg3(NO3)12∙24H2O have been calculated from the known and new perturbation mechanisms up to and including fourth order, using the relativistic wave functions. It is shown that the largest contribution to the observed value of D is due to the second-order perturbation mechanism, in agreement with the prediction of van Heuvelen.
