Investigations of the Isotropic G Factors for the Cubic Fe⁺ Centers in LiF and NaF

Abstract:

The g factors for the cubic Fe⁺ centers in LiF and NaF are theoretically investigated from the perturbation formula of the g factor for an octahedral 3d⁷ cluster including the contributions from the ligand orbital and spin-orbit coupling interactions. The increasing order of the g factor (i.e., LiF < NaF) can be ascribed to the decrease in covalency and the strength of cubic crystal-field of the systems. The validity of the results is discussed.
