摘要：

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. © 1968 The American Institute of Physics.
