| 摘 要： | 用双SO耦合模型推导了立方晶场中3d4/3d6离子5D态的哈密顿矩阵公式(25×25阶).用该公式计算了晶体ZnSe∶Fe2+的基态精细结构分裂，研究了在外磁砀为0—30T范围以及在［100］和［111］方向的Zeeman分裂、Raman移动和磁化强度.理论计算与实验符合很好.

| Abstract: | The Hamiltonian matrices formulae of 5D state for 3d4/3d6 ions in cubic symmetry are derived using a two spin-orbit (SO) coupling parameter model. The Hamiltonian matrices are 25×25(5D) dimensions. On the basis of the formulae, the fine-structure splittings of the ground state in cubic ZnSe∶Fe2+ crystal are calculated. The Zeeman splitting,the Raman shift and the magnetization in magnetic fields up to 30T along the ［100］ and ［111］ directions are investigated, respectively. The present results are in excellent agreement with the experimental ones. |
