“…We also do not expect significant changes of the parameters U (4) , b 4 (κt) and X (κt)4 because these two ions are very similar. The inadequacy of a model in which the RE ion interacts with the enviroment by electrostatic crystal field potential only has been already noticed in the literature 5,8,9 . In 1978 Barnes et.…”

We propose a new mechanism leading to the ground state splitting for the rare earth 8 S ions in semiconductor crystals. The resulting splitting is due to three effects, the first is the intra atomic 4f − 5d spin-spin interaction, the second one is the spin -orbit interaction for 5d electrons and the third one is their hybridization with the valence band states of semiconductors host. The resulting splitting significantly depends on the relative position of 5d level with respect to semiconductor host band structure. We also discuss different model, already known in the literature, which is also based on ion -band states hybridization. For both models, as an example, we present results of numerical calculations for rare earth ion in IV-VI semiconductor PbTe.

“…The usual Stevens operators [1,2] in EMR studies [27,28] and to a lesser extend in the crystal field theory and superposition model analysis [29,30,31]. Group theory predicts that for lower symmetry cases the negative q components are required [2,3,4].…”

“…Correlation of the axis systems assigned to experimentally determined ZFSP sets may be possible by comparison with model calculations using, e.g. superposition model analysis [29][30][31], which must be carried out in a well-defined axis system, usually the crystallographic one.…”

“…Since the SM was introduced by Newman and his co-workers 7,9 to successfully analyse the CFP of lanthanide ions in various garnets and other crystal systems 10 , its equation and formalism had been widely extended to model the spin-Hamiltonian parameters (SHP) for the zero-field splittings of the ground 8 S 7/2 state of the 4f 7 (Gd 3+ and Eu 2+ ) ions or ground 6 S 5/2 state of 3d 5 (Fe 3+ and Mn 2+ ) ions [11][12][13] , even though the contributing mechanisms to SHP are substantially different from those of CFP. For analyzing the crystal field splittings of the 3d transition-metal ions, the examples of SM application were relatively fewer [14][15][16] because of the rather limited number or incomplete set of CFP derived from some experimental energy levels of which their states are often poorly determined or identified.…”
