Abstract
The existence of propagating spin waves above Tc in Ni and Fe has been widely accepted since this picture was first advocated in 1973. In this brief review of our current neutron scattering experiments on Fe and Ni we will present convincing evidence showing that this picture is incorrect. In addition, we will demonstrate that over wide ranges of ω, q and temperature, both Fe and Ni follow a simple paramagnetic scattering function of the spin diffusion type.
