Semiempirical Relation between Hyperfine Constant and Charge Amount of Doped Mn²⁺ Ion in Non-Metallic Compounds

Abstract

A semiempirical relation is given between the number of electrons transferred to the empty orbits and the hyperfine constant of the doped Mn²⁺ ion in various compounds, on the basis of the empirical relation between the Szigeti charge and the hyperfine constant of the doped Mn²⁺ ion in the divalent metal compounds and of an assumption that the charge of the impurity ion is equalized to that of the host cation when the impurity replaced the host cation having the same valence as the impurity. The derived semiempirical relation is applied to a problem of the degree of the localization of the bound hole to the doped Mn²⁺ ion in the III V semiconductors. The bound hole is shown to be almost completely localized on the Mn orbits.
