Abstract

We study, using finite temperature Monte Carlo simulations, the demagnetization curves, coercivity, and energy product of multilayers of hard (Nd2Fe14B) and soft (FeCo) magnetic material. The easy axes of the hard and soft phases are parallel to the layers. We perform simulations with and without the dipolar interaction, with periodic and free boundary conditions, and find a significant influence of the dipolar interaction on the coercivity and the energy product.
