Paramagnetic resonance study on transition metal ions in phosphate, fluorophosphate and fluoride glasses, part I: Cr 3+ and Mo 3+

Abstract

The ESR of Cr 3+ in phosphate, fluorophosphate and fluoride glasses has been studied. The energy level splitting and the effective g value of the Cr 3+ ion have been calculated with the spin-Hamiltonian. It is pointed out that the transition can be found not only within every Kramers doublet, but also between two Kramers doublets. The zero field splitting parameters D has been determined: 0.15–0.4 cm −1. In this paper, the ESR of the Mo 3+ ion in phosphate glass is also reported.
