| 中文摘要 | In this paper the spin-lattice coupling coefficients G11 and G44 for Fe3+ ions in both octahedral and tetrahedral sites of YAG crystals have been calculated within the framework of the cubic field approximation from our simple and uniform method of calculating these coefficients in two cubic (O(h) and T(d)) symmetries by using the parameters obtained from the optical spectra. The results can satisfactorily explain the uniaxial-stress EPR experiments for the two sites and are reasonable. On this basis, the parameters alpha and beta that characterize the distributions of internal stresses and strains are determined for the two sites from the distinctive linewidth data of EPR spectra. It appears that our above method can be used to study the internal stress distributions for the crystals containing paramagnetic ions, particularly in the absence of experimental data of spin-lattice coupling coefficients. |
