Investigations on the Gyromagnetic Factors for the Layered Triangular Antiferromagnets VX2 (X = Cl, Br, I)

Shao-Yi Wu, Xiu-Ying Gao , Qiang Fu and Ji-Zi Lin

Abstract:
The gyromagnetic factors g// and g for the layered trigonal antiferromagnets VX2 (X = Cl, Br, I) are theoretically investigated by using the perturbation formulas of the g factors for a 3d3 ion in trigonal symmetry based on the cluster approach. In these formulas, the contributions from the s-orbitals of the ligands which were often ignored in the previous treatments are taken into account here. The related trigonal field parameters V and V ’ are determined from the superposition model and the structural data of the systems. The calculated g factors are in good agreement with the observed values, particularly the results for VI2 show some improvement compared with those in the absence of the ligand s-orbital contributions.
