“…The first arises from the electrostatic interaction between a 3d ion and ions of crystal lattice (treated as the point charges, without taking into account their electron structure), and the second one is proportional to the overlap of the wave functions of a central ion and ligands. Originally the ECM was proposed by Malkin [8] for rare earth ions, but later it has also been successfully applied to the transition metal ions in different hosts ( [9][10][11][12][13][14][15][16] and references therein).…”

The present work is devoted to the crystal field analysis of trivalent chromium doped in SrAl 2 O 4 spinel in the frame of the exchange charge model of crystal field. Using the shell model and pair approximation, we optimize the geometric structure of the crystal. The approach enables the modeling of the crystal field parameters and thus calculates the energy level scheme of Cr 3+ ions in spinel SrAl 2 O 4 . The obtained results are compared with experimental data and discussed.

The aim of this paper is to investigate, from theoretical point of view, the optical spectra and EPR (g-factors) parameters for Mn 4+ :LiGa 5 O 8 . The optical energy levels scheme has been obtained by the diagonalization of the Hamiltonian of the system, using all 50 wave functions of the LS terms of 3d 3 electron configuration. The crystal field parameters have been obtained in the exchange charge model of crystal field, taking into account the structure of the host matrix and effects of the covalent bond formation between the Mn 4+ with O 2− . The satisfactory agreement with experimental data is obtained.
