Abstract
Although spin disorder should lead to a broadening out of the sharp spin-wave-Stoner-mode intersection point observed in iron and nickel above their Curie temperatures, no such broadening has been seen. In this article, the observed relatively rapid fall off of the spin-wave neutron scattering intensity when the spin wave enters the Stoner continuum is interpreted using a theory of broadening of the spin-wave line due to spin disorder proposed by Liu.Keywords
