摘要: 本文利用SCF-d轨道理论,采用d5离子低对称场下的高阶微扰零场分裂公式,对YAG:Mn2+的零场分裂进行了理论计算,得到了与实验相符合的理论结果.从而解决了多年来YAG:Mn2+的EPR谱中理论与实验不符的困难.

关键词: YAG:Mn2+, 零场分裂, 电子顺磁共振

Abstract: By use of SCF d-orbital theory and high order perturbation formulas for the zero-field splitting of d5 ion at low symmetry, the zero-field splitting of YAG:Mn2+ was calculated and a result with good agreement with the experiment. The difficulty which could not be overcome for years in the theory of EPR spectrum of YAG:Mn2+ has been solved.

Key words: YAG:Mn2+, Zero-field splitting, EPR
