摘要：

Magnetization and susceptibility measurements performed on single crystal Erbium Iron Garnet (ErIG) are presented over the temperature range 4.2-6O0 K in a field up to 30 kOe applied along the [111] direction. Important differences from polycrystalline sample results are obtained. The magnetic susceptibility follows a Curie Weiss law; but two values of the paramagnetic Curie temperature and of the Curie constant in the two temperature ranges separated by the compensation temperature are found. At low temperature, the exchange interactions between Er3+ ions are not negligible compared to the iron-rare earth interactions. The molecular field coefficient which represents these last interactions is found to be strongly temperature dependent.
