Studies of EPR g-factors on Rutile (TiO₂) with Co²⁺ Ion

Abstract

The anisotropic g-factors g X , g Y , and g Z for Co 2+ in rutile crystal are studied from the secondorder perturbation formulas based on the cluster approach. In the studies, the contributions due to covalency effects, the configuration interaction and the rhombic crystal field are taken into account. The calculated values are close to the observed ones. The small discrepancy between calculation and experiment is discussed.
