Magnetic anisotropy of YFe3 compound

Abstract Magnetization curves of an YFe 3 single crystal were measured along the basal plane and the c-axis within the temperature range of 2–600 K. Their analysis provided temperature dependencies of the parameter p = ( M ep − M ha ) / M ep characterizing saturation magnetization anisotropy and magnetocrystalline anisotropy constants K 1 and K 2 . The latter was obtained using the modified Sucksmith-Thompson method and the numeric technique of approximation which takes into account slight misorientation between applied magnetic field and the hard magnetization axis allowing to describe magnetization curves accurately.
