Description

We have performed a neutron scattering study of the spin correlations in the amorphous alloys (Fe/sub 1-x/Mn/sub x/)75P16B6A13 with x = 0.35 and 0.25; the former exhibits short-range spin correlations at all temperatures. The latter displays a paramagnetic-ferromagnetic transition followed by a gradual evolution into a state characterized by Q/sup -2.6/ power-law decay at low temperatures. We present a simple model for this behavior based on random field effects
