摘要:

According to a straightforward method, the spin-lattice coupling coefficientsG11andG44for MgO: Fe3+crystal are calculated theoretically by using the formulas obtained from the spin-orbit coupling mechanism and the relativistic mechanism. Based on this, the local strains in the vicinity of Fe3+ion, which is different from the bulk ones, have been investigated. The results are compared with those obtained from the superposition model analysis.
