| 摘 要： | 考虑到Mn~(2+)在钇铝榴石Y_3Al_5Si_3O_(12)(YA1G)中占据三种不同的晶位,本文推导出D_(2d)、D_(3d)和D_2低对称晶场下3d~5离子零场分裂常数D值和E值的四阶微扰公式。我们把该公式应用于YA1G:Mn~(2+)的D值和E值的计算,结果与实验值较为接近。

| Abstract: | Considering the occupation of three different crystallographic sites by Mn~(2+) in yttrium-aluminium garnet (YAIG), in this paper we have derived the formulae of four-order perturbation for the zero-fleld splitting parameters D and E for 3 d~5 configuration in the low-symmetry crystal field (D_(2d), D_(3d) and D_2). With these formulae, parameters D and E of YAIG: Mn~(2+) were worked out. The calculated values are consistent with the experimental results. |
