Abstract We apply the hybrid Monte Carlo (HMC) micromagnetic method to FeCo soft magnetic polycrystalline films and test the new method by comparing with the result worked out by micromagnetics using Landau–Lifshitz–Gilbert equations, and the magnetic properties of FeCo films are understood better by carefully considering the effects of polycrystalline microstructures. The hysteresis loops of the FeCo film from low temperature up to 1100 K are simulated by the new HMC micromagnetic method.
