The coercive force, Hc and magnetostriction, λs, have been measured for nonequilibrium Fe1-xPdx alloys, with increasing x, Hc decreases but λs, increases. The decrease of Hc may be related to the decrease in the average anisotropy due to the reduction of crystal grain size. After annealing above 600K, Hc increases rapidly because of the precipitation of the ordered FePd phase.

M?ssbauer spectra were taken at 4.2 K and 290 K for the bcc and fee Fe1-xPdx alloys produced by vapor quenching. The hyperfine interaction parameters and hyperfine field distribution curves were obtained with spectrum fitting method. With increasing x, the average hyperfine field, Hhf increases in bcc Fe1-xPdx alloys, while Hhf decreases in fee alloys. The concentration dependence of Hhf can be explained by using a semi-empirical formula.
