Abstract

The magnetic susceptibility c and the electrical resistivity σ of CrGe and Cr11Ge8 are investigated at temperatures above 4.2 K. The magnetic susceptibility of CrGe exhibits a cusp at about 45 K and shows the T2 dependence with positive coefficient at low temperatures. This behavior of CrGe, together with the behavior of ρ, is explained by the paramagnon theory for a nearly ferromagnetic metal. The reciprocal of * of Cr11Ge8 deviates from the Curie-Weiss type relation at low temperatures, and ρ of cGe8 shows tendency of saturation at high temperatures. These behaviors of Cr11Ge8 are explained by the SCR theory for a nearly ferromagnetic metal. The magnetic and electrical properties of CrGe and Cr11Ge8 indicate that the natures of electron correlations of these compounds locate in the intermediate region and the ferromagnet Cr11Ge19.
