Description
The effect of the Jahn-Teller interaction on the giromagnetic factor g is calculated for the ground state of a substitutional Co2+ in crystalline MgO. In the model employed, only the interaction between Co2+ and the six nearest O2- is considered, and their displacements from the equilibrium position are expressed as linear combinations of all the phonon modes of the crystal. The phonon spectrum employed is an analytic approximation to the results of a detailed calculation of another author. The effects of covalence are also taken into account in the present model.

O efeito da interacao Jahn-Teller sobre o fator giromagnetico g e calculado para o estado fundamental de um ion Co2+ substitucional em MgO cristalino. no modelo usado, somente e considerada a interacao entre o Co2+ e os seis O2- mais proximos, e seus deslocamentos da posicao de equilibrio sao expressos como combinacoes lineares de todos os modos fononicos do cristal. O espectro de fonons utilizado e uma aproximacao analitica dos resultados do calculo detalhado de um outro autor. Os efeitos da covalencia sao levados em conta no modelo. (Autor)Additional details
