Description
Summary:Characteristics of the electron paramagnetic resonance (EPR) spectra of the Mn2+ ion in the oxyfluoride glass ceramics containing SrF2 crystalline counterpart has been investigated. Explicit superhyperfine structure (SHF) has been observed in the X-Band EPR spectra taken at 77 K after thermal treatment of the glass precursor. Such SHF structure is characteristic to Mn2+ ion in the fluorine coordinated nearest environment which is characteristic to cubic structure of the alkaline earth fluorides. Manganese replaces strontium in the SrF2 lattice where it has pronounced SHF interaction with surrounding fluorine nuclei. Thus Mn2+ ion provides information about crystalline structure of the particular oxyfluoride glass ceramics.
