| Abstract: | The results of a single crystal neutron diffraction study of europium selenide EuSe in zero external magnetic field are reported. At 4.2°K europium selenide is antiferromagnetically ordered according to an oscillating type of spin configuration. Partial ferromagnetism is observed at 1.9°K, in agreement with previous measurements [1, 2]. Concerning this low temperature phase a model with two coexistent magnetic phases is proposed. |
