Title:
Paramagnetic Neutron Scattering from the {{Heisenberg}} Ferromagnet {{EuO}} 
Abstract:
Paramagnetic neutron scattering from the insulating Heisenberg ferromagnet EuO has been studied through the entire Brillouin zone. The measured linewidth $\Gamma$ of the quasielastic scattering at Tc follows the predictions of dynamic scaling $\Gamma$=Aq2.5 up to momentum transfers q=0.4 A˚-1. The new results disagree with an early work by Passell et al., where a smaller exponent and smaller linewidths have been reported, but agree perfectly with recent spin-echo measurements performed by Mezei...    »
