TEMPERATURE DEPENDENCE OF THE FIRST AND SECOND ORDER MAGNETOCRYSTALLINE ANISOTROPY CONSTANTS IN EuS

G. Everett , R. Ketcham

The first and second order magnetic anisotropy constants, K1 and K2, have been measured in the fcc insulating ferromagnetic compound EuS, as a function of temperature. They have been determined from the angular dependence of the ferromagnetic resonance at 24 GHz in single crystal-single domain samples. The single ion mechanism of Wolf is not sufficient to explain the results. It is suggested that the observed results can be interpreted as the sum of a single ion and magnetoelastic contribution to the anisotropy energy.
