We have observed, in our dc magnetization studies, the peak effect (PE) in the superconducting mixed state of two compositions, Mo0.825Re0.175 and Mo0.8Re0.2, of the binary alloy system Mo1−xRex. The PE occurs close to the H c2(T) line at temperatures below T C, similar to the well studied compound CeRu2. A detailed investigation of the various characteristics of this peak effect and a comparison with other superconductors of current interest show that the observed behaviour can be explained within the realm of critical state models of hard type-II superconductors. Our results show that the anomalies reported in CeRu2 and NbSe2 are not universal to materials showing a PE close to the H c2(T) line and may, therefore, have an important bearing on the phenomenology of type-II superconductors.
