采用了中间场耦合图像 ,考虑了以前研究中被忽略的SS (spin spin)磁相互作用以及SOO (spin other orbit)磁相互作用 ,利用完全对角化方法 ,研究了 3d2 态离子在三角对称 (C3v,D3,D3d)晶体中自旋哈密顿 (SH)参量的微观起源 .发现自旋哈密顿参量 (包括零场分裂参量D和g因子g∥ ,g⊥)来自四种耦合机理 :(1 )SO (spin orbit)耦合机理 ;(2 )SS耦合机理 ;(3)SOO耦合机理 ;(4 )SO SS SOO联合耦合机理 .对于SH参量 ,虽然SO耦合机理是最为重要的 ,但其他三种耦合机理对零场分裂参量D的贡献不可忽略
The mid-field coupled images are considered, the neglected spin-spin (SS) and spin-on-the-rest (SOO) magnetic interactions in the previous study are considered. By using the complete diagonalization method, C3v, D3, D3d). The spin Hamiltonian (including the zero-field splitting parameters, d and g, g∥, g⊥) are found to originate from four coupling mechanisms: (1 ) SO (spin orbit) coupling mechanism; (2) SS coupling mechanism; (3) SOO coupling mechanism; (4) SO SS SOO joint coupling mechanism. Although the SO coupling mechanism is the most important for SH parameters, The contribution of coupling mechanism to zero field splitting parameter D can not be neglected
