抜粋

The magnetic susceptibility x and the electrical resistivity σ of Cr1_xFexGe (0<x<0.9) are measured in the temperature ranges of 4.2-420 K and 4.2-300 K, respectively. The magnetic susceptibility shows the Curie-Weiss-like behavior in a composition region close to a critical composition for the onset of ferromagnetism (x=0.75). At high temperatures, the electrical resistivity shows a temperature dependence which is convex to temperature axis and finally tends to saturation for all the samples investigated. For small x, the electrical resistivity is proportional to T2 at low temperatures. These behaviors of x and p for x>0 are explained on the basis of the spin fluctuation theory for weakly and nearly ferromagnetic metals. We conclude that the degree of the electron correlation increases systematically with increasing x.
