Abstract
A study of the inelastic neutron scattering from antiferromagnetic RbMnF3 in the vicinity of the Néel point reveals the presence of a diffusive‐type peak, accompanied by spin‐wave modes that persist above the transition temperature. The width of the diffusive peak for small‐momentum transfer is found to be strongly temperature‐dependent above TN, indicating a slowing down of the spin fluctuations near the transition.Keywords
