摘要：

Magnetoresistance, thermopower, Hall resistivity, ac susceptibility and magnetization have been measured for CeRu2 in the normal and superconducting phases. In the normal state, there is a magnetic anomaly at 50 K, which is presumably due to development of antiferromagnetic order. The H-T superconducting phase diagram obtained from ac susceptibility indicates the possibility of multiple superconducting phases.
