Magnetic Properties of the Pd and Pt Group Transition Metal Complexes

Abstract

The magnetic susceptibilities and the g-values of the Pd and Pt group transition metal complexes are calculated by means of the intermediate coupling scheme. Crystalline field with cubic symmetry is assumed to be strong, so that the effect of dγ orbitals is neglected. The effect of Coulomb repulsion is considered to be comparable with that of the spin-orbit interaction. The results are expressed by functions of parameters η=ζ_d⁄(3B+C) and kT⁄ζ_d, where B and C are Racah’s parameters and ζ_d the coefficient of spin-orbit coupling of a d-electron. Comparison with available experimental data is also made.
