| 摘 要： | 在考虑掺杂晶体局域畸变的影响后, 建立了联系RbMgF3: Ni2+体系的局域畸变结构与EPR谱间的关系, 并计算了RbMgF3: Ni2+晶体在C3v和D3d对称下的零场分裂参量和g 因数. EPR谱的理论计算值与实验值符合甚好.

| Abstract: | Taking account of the effects of local distorted structure of the doped crystal, the relationship between the local distorted structure and the EPR parameters was established for RbMgF_3: Ni 2 system. The zero-field splitting parameter D and the g factors for Ni 2 ions in RbMgF_3 crystals with C_ 3v and D_ 3d symmetry were calculated, and found to agree well with the experimentally measured values. |
