The ferrimagnetic multilayer system with disordered interfaces

Abstract

The magnetic properties (Transition temperature and magnetizations), of a aferrimagnetic multilayer system consisting of L layers of spin-1/2 A atoms, L layers of spin-1 B atoms and a disordered interface in between that characterized by a random arrangement of A and B atoms of A_pB_{1-p} type and a negative A-B coupling, are studied within the framework of an effective-field theory. The effect of the disordered interface, interactions and different anisotropies on the magnetic properties are examined. The obtained results show a number of characteristic features, such as the possibility of two compensation points.
