摘要: 采用双自旋-轨道耦合模型和分子轨道研究了Co2+离子在Ⅱ-Ⅵ半磁半导体ZnS和CdTe中的EPR g因子.计算表明,配体Te有大的SO耦合作用和强的共价性,其对g因子有较大的贡献.

关键词: 双SO耦合, ZnS:Co2+和CdTe:Co2+, EPR g因子

Abstract: In this paper the EPR parameters g for Co2+ ions in Ⅱ-Ⅵ semimagnetic semiconductors ZnS and CdTe were studied by means of a double spin-orbit (SO) coupling model and a molecular orbit. The calculated results show that the contribution from the ligand Te to the EPR parameter g can not be neglected because the ligand Te possesses large SO coupling constant and strong covalence.

Key words: Double SO coupling, ZnS:Co2+ and CdTe:Co2+, EPR parameterg
