Comparison of the critical magnetic scattering from the Heisenberg system EuO with renormalization-group theory

Abstract
The paramagnetic scattering from the isotropic Heisenberg ferromagnet EuO has been investigated by inelastic neutron scattering in order to test the predictions of asymptotic renormalization-group theory. The scattering cross sections are in excellent agreement with theory over a wide range of momentum and energy (q̊1, ω
