Mössbauer spectrum depending on the degree of spin‐system ordering

Abstract

A theoretical investigation is made of the Mossbauer spectrum in crystals containing exchange coupled magnetic ions. It is shown that for a Lorentz shape of the Mossbauer line the line broadening, the Debye-Waller factor describing the intensity of the Mossbauer spectrum, and the line shift depend on the value of exchange interaction of magnetic ions and on the degree of spin-system ordering.
