Investigation of the EPR Parameters of an Orthorhombic Cu

In the calculations, the crystal-field parameters are obtained by the superposition model, and the impurity-induced local lattice relaxation (which is similar to that found for Fe 3

Substituting these parameters into the above formu- las and diagonalizing the complete energy matrix, the anisotropic g-factors for Cu 2+ and the hyperfine struc- ture constants A

It is found that the oxygen octahedron sur- rounding the impurity ion V 4 + changes from elongation along the tetragonal axis in the pure crystal to compression and the magnitude

Noteworthy, for the 3d 1 ions Ti 3+ and Cr 5+ in the tetragonal phase of SrTiO 3 [28, 29], since ¯ R > R ⊥ , the ground state is an orbital doublet, an additional distortion due

In these formulas, the J- mixing among the 6 H J (J = 5/2, 7/2 and 9/2) states via crystal-field interactions, the mixtures among the states with the same J value via

In these formulas, the J- mixing among the 6 H J (J = 5 / 2, 7/2 and 9/2) states via crystal-field interactions, the mixtures among the states with the same J value via

In these formulas, the contributions to the EPR parameters arising from the second-order perturbation terms and the admixtures of different states

2) Based on the calculations, we find that the con- tributions to g or A due to the second-order pertur- bation terms amount to about 9 ∼ 10% of those due to the
