摘要：
Cr1-xVxSi2 solid solutions have been prepared in the range 0 less than or equal to x less than or equal to 1. The thermopowers, resistivities, and magnetic susceptibilities of the solid solutions vary smoothly with composition and reveal a continuous transition from degenerate semiconducting (x = 0) to metallic (x = 1) behavior. S-2/rho ratios of the solid solutions are less than those of pure CrSi2. The thermoelectric properties of the solid solutions can be described in terms of a free-electron model, whereas an effective mass of 15 m(c) has to be assumed in order to explain the results of magnetic measurements.
