Abstract
The susceptibility, magnetic moment, and resistivity of an alloy of CeRu2+7.3% GdRu2 prepared by arc melting have been measured in the range 1.3° to 20°K. This alloy has been previously reported to be both ferromagnetic and superconducting. The sample is weakly ferromagnetic, and undergoes a superconducting transition which reduces the positive susceptibility. The resistance becomes smaller at the transition temperature, but does not become zero. The transition temperature in zero field is in good agreement with that previously reported.
