Abstract

Spin wave resonances, observed in an amorphous Gd6.9Co74Mo12.8Ar6.3 ferrimagnetic alloy film, indicate that the exchange stiffness constant, A, decreases rapidly with increasing temperature. By extension of spin-wave theory to ferrimagnets, the temperature dependence of A has been interpreted in terms of a two sub-network ferrimagnet.(AIP). © 1979, American Institute of Physics.
