Abstract

The results of magnetic susceptibility, heat capacity (C), electrical resistivity (ρ) and magnetoresistance measurements on the alloy CeCu0.86Ge2 are presented. This alloy exhibits the following characteristics: (i) and 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 10-20 kOe; and (iii) an increase of C/T and a decrease of ρ below 5 K, which does not seem to arise from another magnetic transition.
