Simulation of Exchange Bias by Two-Phase Ferrimagnetic Model Using Antiferromagnetic Interlayer Coupling for the Fe₃O₄ Thin Film

抄録

We conducted a theoretical study on a phenomenon where an exchange bias effect appears in a Fe₃O₄ thin film containing an opposite phase boundary when a two-phase ferrimagnetic model is introduced using antiferromagnetic interlayer coupling. We studied the simulation technique for such a system and derived magnetic hysteresis loops in the exchange bias effect by computer simulations using the retarded-trace method.
