The authors report the results of specific heat measurements, between 0.3K and 10K, in magnetic fields up to 75 kOe, on the 'nearly ferromagnetic' amorphous alloy Y_0.22Ni_0.78. The results, especially the magnetic field dependence, exclude any appreciable contribution from uniform paramagnons. In contrast a quantitative analysis is obtained in terms of superparamagnetic clusters, demonstrating that the onset of ferromagnetism, as a function of concentration, is inhomogeneous in this amorphous metallic system.
