Abstract
The first-order cubic anisotropy constant in EuO single crystal was measured as a function of temperature and applied field by the static torque method. The value at K is erg/. The variation of with and is uniquely described by the behavior of the measured magnetic moment . The observed relationship between and is explained by a theory of single-ion interaction with the cubic crystal potential. The cubic crystal-field splitting parameter /ion obtained from is compared with results for ions in various other materials.
