Abstract
The x dependence of the magnetic susceptibility chi(0) and of the coef ficient gamma of the linear term of the specific heat of the series Ce (Co1-xNix)(2) show a minimum around 0.67. This is possibly due to a cr ystal field effect. The high field differential susceptibility data re veals that the 4f electron of cerium is in a 'Gamma(7) like' state and that even if the valence of cerium is constant, chi(0) and gamma woul d increase with x for x > 0.67.
