Abstract

Neutron inelastic scattering measurements have been performed on amorphous Fe₇₀Ni₂₀Zr₁₀. Spin waves were observed in the wave vector range 0.07 Å^-1≤q≤0.12 Å^-1 at temperatures 0.55T_c≤T≤0.89T_c. The spin-wave energies were well described by E=Δ+D(T)q². The stiffness constant D(T) renormalizes as D(T)=D(0)[1+0.68(T/ T_c)^{5 2}], D(0)=(110.9±1.5) meV Å². D(0) is about 1.5 times the value calculated from magnetization measurements.
