| Abstract | In this paper, by introducing a factor f to denote the contraction effect of perovskite crystals along the trigonal axis in the cubic-to-trigonal phase transition, the expressions for calculating the zero-field splitting D, the first excited-state splitting Delta((2)E),and the anisotropy of the EPR g-factor (characterized by Delta g = g(parallel to) - g(perpendicular to)) for 3d(3) ions in the trigonal phase of this pervoskite structure from the rotation angle alpha have been put forward. On the basis of these expressions, the zero-field splitting D, the splitting Delta((2)E) and the anisotropy of the g-factor for Cr3+ in the trigonal phase of a LaAlO3 crystal are calculated by using two parameters obtained from the optical spectra of a similar crystal. The results show reasonable agreement with the experimental values. |
