013, India Abstract. Superconductivity in CeRu2 was discovered 40 years ago, and was extensively studied because alloying with magnetic elements showed the coexistence of superconductivity and magnetic order. The normal state of CeRu2 has been of interest because of its intermediate valence character. The superconducting state has been studied extensively because of its paramagnetic nature and anomalous pinning properties. This review presents the present status of knowledge, and discusses the puzzling features of CeRu2. Keywords. CeRu2; intermediate valence; normal and superconducting state; peak effect.
