Summary
A uniform und simple method suitable to alld n ions is established for the calculation of spin-lattice coupling coefficientsG 11 andG 44 inT d symmetry. According to the method, the coefficientsG 11 andG 44 for Fe3+ ion in GaP crystal have been obtained from the high-order perturbation formulae of zero-field splitting in tetragonal and trigonal fields based on the spin-orbit coupling mechanism. The calculated results show good agreement with the experimental findings.
