Temperature Dependences of the Constants of Magnetic Anisotropy of Single-Crystal MnSb Inclusions in an InSb Matrix

Contributions from constants K1 and K2 of first- and second-order magnetic anisotropy to the effective constant are separated. Their competition determines the type of easy-plane magnetic anisotropy. Extrapolating dependences K1(T) and K2(T) to the region of high temperatures allows the prediction of temperature TSR = 570 K of the spin-reorientation transition, during which easy-axis magnetic anisotropy is formed.
