MAGNETIC-BEHAVIOR OF CECU0.86GE2

The results of magnetic susceptibility, heat capacity (C), electrical resistivity (rho) and magnetoresistance measurements on the alloy CeCu 0.86Ge2 are presented. This alloy exhibits the following characteristi cs: (i) an antiferromagnetic ordering at a rather high temperature (15 K) in spite of the fact that the Curie-Weiss parameter is positive; ( ii) a sharp metamagnetic behaviour below 15 K in a magnetic field of 1 0-20 kOe, and (iii) an increase of C/T and a decrease of rho below 5 K , which does not seem to arise from another magnetic transition.
