Electron spin resonance of transition metal ions in glasses

Abstract

Electron spin resonance (ESR) studies of transition metal ions in glasses have been briefly reviewed. The known relations of spin Hamiltonian parameters to structural geometries around the transition metal ion probes in glasses are summarized. Recent ESR studies in glasses based on the use of Ti³⁺, VO²⁺, Mo⁵⁺, Cr³⁺, Fe³⁺, Mn²⁺ and Cu²⁺ have been emphasized. Merits of ESR in the context of structural elucidation have also been discussed.
