Abstract

Magnetic susceptibility Χ(T), electrical resistivity ρ(T) and magnetoresistivity of CePt₂(Si_1-xGe_x)₂ alloys (0 ≤ x ≤ 1) are reported. For Χ(T) of these, the Curie-Weiss relationship is followed with effective moments in close agreement with μ_eff = 2.54 μ_B expected for Ce³⁺ . A maximum in ρ(T) is observed at a temperature T_max ̃ T_K ̃ exp(-1/|JN(E_F)|). From the decrease in T_max with increasing x it is deduced that |JN(E_F)|_x=0 =0.11 ± 0.02.
