Exchange bias study in FM/AFM bilayers: Atomistic simulations
Year: 2025
Type: article
Abstract: The exchange bias (EB) effect has been studied through simulations utilizing the Landau–Lifshitz–Gilbert equation and the Heisenberg spin model in a Ferromagnet/Antiferromagnet bilayer system where the Antiferromagnet layer near the interface is modified by disturbing the AFM order. As an immediate effect of the disturbance of AFM order, the M-H loop of the bilayer broadens and also becomes asymmetric. Therefore the artificial heterostructure exhibits the bias field, suggesting a way to tune the exchange bias effect for scientific applications.
