On the hyperfine structure of the Mn²⁺ EPR line with <i>g</i> = 4.3 in chalcogenide glasses of some ternary systems

Abstract

Abstract EPR of Mn 2+ ions in glasses of ternary systems MAsSe (M = Cu, Zn, Ge, Ag, Hg, Tl, Pb, Bi), PGeSe, IAsX (X = S, Se, Te) of different compositions and in glassy As 2 Se 3 are studied. The dependence of the Mn 2+ EPR spectra on frequency, temperature, impurity concentration, and glass composition is observed. The complex HFS structure of the g = 4.3 line is explained by superposition of two sextets with a shift of the isotropic g ‐factor of ≈︁0.08. The model of the Mn 2+ incorporation into the glass network is proposed. A high regularity of Mn 2+ surroundings is explained by a high degree of short range order in the glasses investigated.
