Effects of the magneto-crystalline anisotropy on the magnetic properties of Fe/Cr/Fe(110) trilayer

摘要

In this paper we present a theoretical study about the influence of the magneto-crystalline anisotropy on the magnetic properties of magnetic metallic trilayers Fe/Cr/Fe (110). The theory is based on a realistic phenomenological model which includes the following contributions to the free magnetic energy: Zeeman, cubic and uniaxial anisotropy, as well as bilinear and biquadratic exchange energies. The experimental parameters used here are based on experimental data known from the literature. We present numerical results of magnetization versus external applied field to illustrate the behavior of the system. Our numerical results show that in some situations the saturation field can not be correctly determined by magnetoresistance measures.
