Abstract This paper presents a cluster approach to the zero-field splitting (ZFS) of the ground state 3A2(F) of d8 ions with tetragonal symmetry, in which not only the spin-orbit coupling of the central transition-metal-ion but also that of ligands contributes. For some pseudo-tetragonal Ni(II) com­ pounds the calculated values of the ZFS parameter follow the order Cl-> Br-> I-. This agrees with the experimental finding, while the pure crystal field approach considering only the coupling of central metal ion yields the opposite trend.

Distortion Parameters

By diagonalizing the complete energy matrix of a d4 configuration ion in tetragonal symmetry, the zero-field-splitting parameters a, D and F of InP:Cr2+ have been studied. The local structure distortion parameters ΔR = 0.08 Å and Δθ = 1.01◦ were estimated. They show an expansion distortion around Cr2+ in the InP semiconductor. The Jahn-Teller energy EJT is found to be about 413 cm−1, which agrees well with the experiment. - PACS numbers: 75.10.Dg; 76.30.-v
