Non-Landau Damping of Magnetic Excitations in Systems with Localized and Itinerant Electrons

We discuss the form of the damping of magnetic excitations in a metal near a ferromagnetic instability. The paramagnon theory predicts that the damping term should have the form γ(q,Ω)â̂ Ω/Γ(q), with Γ(q)â̂ q (the Landau damping). However, the experiments on uranium metallic compounds UGe2 and UCoGe...
