摘要/Abstract

摘要： 本文报道用晶体场理论对新型稀磁半导体 Zn_1-xCo_xSe和Zn_1-xCo_xS 中Co²⁺离子不同能级间的跃迁进行计算的结果。与实验观测结果进行了比较，获得了相应的晶场参量D_q，Racah静电参量B，C和自旋－轨道耦合参数λ。本文对 Zn_1-xCo_xSe和Zn_1-xCo_xS分别指认了观测到的Co²⁺离子能级间的跃迁。对较低能级部分，实验结果与理论计算符合较好。

Abstract: Spectra of the new type diluted magnetic semiconductors Zn_1-xCo_xSe and Zn_1-xCo_xS related to transitions between the dif-ferent energy level of Co²⁺ ions for states of d⁷ configuration have been calculated by crystal field theory. The comparison of calculated and observed spectra of Co²⁺ ions have been given. Bothare in good agreement in the low energy level part. Crystal field D_q, Racah B, C and spin-orbit coupling λ parameters have been obtained and observed spectra of Co²⁺in Zn_1-xCo_xSe and Zn_1-xCo_xS have been designeted, respectively.

Key words: diluted magnetic semiconductors, crystal field, spin-orbit coupling
