A neutron polarization analysis study of Ce2Fe17 in its paramagnetic phase

Abstract: Spin-flip (paramagnetic) scattering and neutron depolarization studies were performed on Ce2Fe17 in its paramagnetic phase on the Dhruva neutron polarization analysis spectrometer. The absence of normalQ dependence of the scattered spin flip intensity shows that Ce2Fe17 is not a normal paramagnetic and there exist superparamagnetic clusters of sufficiently large dimensions (∼100A). The observed neutron depolarization gives an indication of the dynamics of these Ce2Fe17 superparamagnetic clusters.
