| 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. |

| Keywords: | Double SO coupling ZnS:Co2+ and CdTe:Co2+ EPR parameterg |
