Computer Simulation of the Bias Field in the Antiferromagnetic-Ferromagnetic Bilayer System

摘要

In this article, computer modeling of the two-layer system is performed. There are two films in the system. The first film is layered antiferromagnetic. The second film is ferromagnetic. The Ising's model is used. A combined approach from the Wolf algorithm and the Metropolis algorithm is used to model the behavior of the system in the magnetic field. Hysteresis loop for various system parameters is obtained. The amount of the bias field is calculated based on the hysteresis loop offset. The bias field is linearly dependent on the exchange interaction at the film boundary.
