摘要：
The effects of substituting rhodium by cobalt in the tetragonal antiferromagnetic compound CeRh2Si2 are studied by x-ray investigation and magnetic, electrical and specific heat measurements. In the Ce(Rh(1-x)Co(x))2Si2 solid solution, a transition from a magnetically ordered state to an intermediate valence state appears when x is nearly equal to 0.135. An increase of the linear coefficient of the specific heat-gamma is observed at this transition. For x less-than-or-equal-to 0.125, the Neel temperature decreases rapidly when x increases.
