description

We investigated the EPR superhyperfine structure of the Mn 2+ ion in the disordered BaF2 crystalline media which tends to crystallize in the oxyfluoride glass-ceramics material. Obtained EPR spectra reveal explicit shf structure due to Mn 2+ ion building into the BaF2 lattice showing its usefulness as a probe in orientationally disordered and amorphous structures. Two types with explicit shf structure of Mn 2+ ion characteristic EPR spectra were obtained in BaF2 powder samples characteristic with broad (type 1) and narrow (type 2) hyperfine structure lines. Spectra of the ZnF2-BaF2 oxyfluoride glass-ceramics samples revealed explicit fine structure lines.
