Temperature dependences of the magnetic anisotropy constants of single-crystal inclusions MnSb in an InSb matrix

Abstract

The contributions of the first order K1 and second order K2 magnetic anisotropy constants to the effective constant are separated. Their competition determines the type of magnetic anisotropy «easy plane». Extrapolation of the dependences K1(T) and K2(T) to the region of high temperatures made it possible to predict the temperature TSR = 570 K, which corresponds to the spin-reorientation transition, at which the easy-axis magnetic anisotropy is formed.
