Description
Summary:The effect of interlayer coupling on the magnetic properties of layered ferrimagnets is studied using spin-wave theory. The sublattice magnetization is calculated for different interlayer coupling strengths and temperatures, and its asymptotic expressions are given in two low-temperature regimes distinguished by the ratio δ of the interlayer and intralayer coupling strengths. It is shown that the interlayer coupling has an important effect upon the magnetic properties of ferrimagnets.
