摘要：

We report a detailed study of magnetoresistance in the intermetallic compounds UCu2Ge2 and (U0.95Ce0.05)Cu2Ge2 in the temperature range of 4.5 to 140 K and in magnetic fields up to 50 kOe. The present measurements support the earlier conjecture drawn from the magnetic studies that the ferromagnetic to antiferromagnetic transition takes place gradually over a wide temperature range. The magnetic-field dependence of magnetoresistance shows that the low-temperature antiferromagnetic state is more fragile in UCu2Ge2 than in (U0.95Ce0.05)Cu2Ge2.
