Abstract

Neutron scattering studies of the magnetic excitations of single crystal specimens of Pd 3Fe and some Pd Fe alloys have been made, using several triple axis spectrometers (TAS) at the ILL, Grenoble. For Pd 3Fe, the renormalisation with temperature of the damped excitations in the “Stoner Continuum” has been observed. The influence of stoichiometry and chemical order has been examined by studies of partially disordered Pd 3Fe and Pd 81Fe 19. For low concentrations of Fe in Pd heavily damped excitations with unusual dispersion have been measured.
