Abstract

The exchange coupling bias field in the antiferromagnetic (AFM) and ferromagnetic bilayer system is investigated within the framework of the classical Heisenberg model. The spin structures in L10-type ordered and disordered γ phase of AFM alloys including magnetic and nonmagnetic atoms are calculated, and the magnetization loops are obtained by using the Landau-Lifshitz motion equation. The AFM layer having the 3Q structure can generate an exchange bias field. However, no magnetization loop shift can be obtained in cases of the IQ, 2Q, and AF-I structures of AFM alloys.
