Abstract

One of the most powerful and reliable methods to directly observe the switching of interlayer coupling magnetization in multilayer films is polarized neutron reflection. In this study, polarized neutron reflection was employed for artificial lattices comprising alternately accumulated ferromagnetic Fe₃Si and semiconducting FeSi₂ layers prepared by facing-targets direct-current sputtering. The switching of interlayer coupling magnetizations was directly observed, which was well consistent with that expected form the magnetization curves.
