Electric-Field Effects in ESR Spectrum of Low-Spin Center Ni3+ in KTaO3 Crystals (Preprint)

Abstract

Electric-field effects in ESR spectrum of low-spin (S=1/2) tetragonal center Ni3+ was studied in KTaO3 single crystals. Orientation of the centers as well as splitting of the resonance lines was found resulting from the external E-field interaction with the electric dipole moment of the center. The value of the dipole moment was determined to be p=103D=21.4 eAngstrom. An analysis of the experimental results allowed us to make a reasonable choice of microscopic models for two nickel centers in KTaO3.
