Abstract: Spin wave resonance in amorphous ferrimagnetic GdCoMoAr alloy film
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.
