An analysis of the quasi-static reversal of magnetization in two-layer films taking into account the effect of the surface binding energy

An analysis is made of the quasi-static reversal of magnetization of two-layer films separated by a dielectric layer, based on the theory of uniform rotation, taking into account the effect of the binding energy, which arises due to the wave-like topography of the ferromagnetic-dielectric boundary surfaces. Theoretical hysteresis loops are given. These are compared with hysteresis loops taken from two-layer films consisting of FeNiMo-Fe separated by a layer of SiO.
