MAGNETIC PROPERTIES OF A SUPERLATTICE OF AMORPHOUS MULTILAYERED FILMS

摘要

Using a finite-cluster approximation, the magnetic properties of a multilayer spin-1/2 superlattice with antiferromagnetic exchange coupling between amorphous magnetic layers across a nonmagnetic spacer are investigated. For reasonable values of the parameters of the proposed model, the magnetic properties of such a system are in agreement with the results observed experimentally on (Fe-Si)/Pd multilayered films. The magnetization exhibits three different kinds of behavior as a function of the amorphization. [References: 29]
