Abstract

By using the spin-orbit coupling mechanism and the empirical superposition model, the zero-field splittings D of Mn2+ ions on both Mg2+ sites in hexagonal 6H-RbMgF3 crystal are calculated from the structural data of both Mg2+ sites. The calculated results of both methods confirm the suggestion that Mn2+ in 6H-RbMgF3 occupies the Mg2+ (I) site (which has D3d site symmetry) and the zero-field splitting D of 6H-RbMgF3: Mn2+ is explained reasonably.
