### Abstract

The magnetic susceptibility χ and the electrical resistivity ρ{variant} of CrGe_{1-x}Si_{x} (0{slanted equal to or less-than}x{slanted equal to or less-than}0.15) are measured in the temperature ranges of 4.2-420 K and 4.2-300 K, respectively. The magnetic susceptibility at high temperatures satisfies the Curie-Weiss type relation: χ = C (T-Θ_{p}), where C(≈0.5 emu K mol) is roughly constant independent of Si content and Θ_{p} decreases from -376 to -462 K with increasing Si content. A maximum or a trace of the maximum is observed around T_{max} in χ for 0{slanted equal to or less-than}x{slanted equal to or less-than}0.15, and this anomalous behaviour becomes indistinct and T_{max} increases with increasing Si content. The electrical resistivity has a T^{2} dependence with large coefficients A (6.3x10^{-9}-10.5x10^{-9} Ω cm{plus 45 degree rule}K^{2}) at low temperatures, and the tendency for saturation is observed in the ρ{variant}-T curve at high temperatures. These behaviours are discussed in terms of the spin fluctuation theory for nearly ferromagnetic metals. We conclude that CrGe_{1-x}Si_{x} (0{slanted equal to or less-than}x{slanted equal to or less-than}0.15) is a nearly ferromagnetic metal and the degree of electron correlation decreases systematically with increasing x.
