| The relations between spin-Hamiltonian parameters and local structure around Cr3+ in diammonium hexa-aqua magnesium sulphate single crystal were established. On the basis of this, the spin-Hamiltonian parameters, optical spectra and the local structure were investigated successfully. The calculated results are in good agreement with experimental data. This shows that the distortion model adopted in this paper is reasonable. |
