Abstract: | This paper explains the Random Field Ising Model simulations of a two-dimensional ferromagnetic/antiferromagnetic interface,
influenced by the exchange-bias interaction. Exchange-biased shifts, coercivity fields, the number of unreversed spins as
well as the numerical errors are provided. These were tested for different structure dimensions and boundary conditions in
order to find limitations of the method. The algorithm developed is simple, very effective, and provides deeper insight into
the nature of the exchange-bias phenomenon. |
