| 摘 要： | 分别采用完全对角化方法和微扰方法讨论了微小磁相互作用对四角对称下基态4B1态和第一激发态2E 态零场分裂的影响. 结果表明，4B1态零场分裂与微小磁相互作用参量成线性关系，2E 态零场分裂主要由二重态决定，磁相互作用和四角晶场对2E 态零场分裂的贡献相比较，四角晶场的作用是主要的.

| Abstract: | Taking slight magnetic interactions(including spin-spin interaction,spin-other-orbit interaction and orbit-orbit interaction) into account and by using complete diagonalization method and perturbation theoretical method,zero-field splitting(ZFS) of()~4B_1 and()~2E states for 3d~3 ions was studied in tetragonal symmetry crystal field.The result show that ZFS of the ()~4B_1 state is linear to the slight magnetic interaction parameters,and ZFS of()~2E state mainly depends on spin doublets. |

| Keywords: | slight magnetic interactions diagonalization zero-field splitting perturbation formula |
