The temperature dependence of optical and EPR spectra for KZnF3∶Mn2+ crystal is studied by considering the contributions from both the static effect and the vibrational effect.The results are discussed.
The EPR parameters (zerofield splitting D and g factors g∥, g⊥) for V2+ ion in YAG crystal are calculated from the highorder perturbation formulas. From these calculations, the defect structure of V2+ center is determined. The results are discussed.
