Magnetization reversal of hard/soft magnetic bilayer

We present a model of hard/soft magnetic bilayer for the Monte Carlo investigation under the external magnetic field. The influence of the exchange interaction constants of soft magnetic layer Jsoft on the magnetic bilayer magnetization reversal processes is explored for the first time. Behavior of the magnetic bilayer under the external magnetic field is shown to agree with theoretical predictions well enough. •The model of hard/soft magnetic bilayer is proposed.•The influence of the exchange interaction constants Jsoft is explored.•Our model is shown to describe well of magnetic properties of magnetic bilayer.
