By taking into account slight interactions, i.e. spin-spin, spin-other-orbit and orbit-orbit interactions, in addition to spin-orbit interaction, the zero-field splitting of ground state and low excited states and g factors of ZnGa2O4:Cr3+ crystal have been interpreted systematically. And the contributions to zero-field splitting arising from slight magnetic interaction and trigonal crystal field are investigated. It is found that there exist combined mechanism between magnetic interactions and trigonal crystal field.
通过考虑除自旋轨道相互作用外的微弱相互作用,即自旋 - 自旋、自旋 - 其他轨道和轨道 - 轨道相互作用,系统地解释了ZnGa2O4:Cr3+晶体基态和低激发态的零场分裂以及g因子。并研究了微弱磁相互作用和三角晶场对零场分裂的贡献。发现磁相互作用和三角晶场之间存在联合机制。
