Abstract
We report the anomalous field (H) dependence of pinning force density FP as deduced from our magnetization measurements on the single-crystal and polycrystalline samples of CeRu2. It is shown that, contrary to a single maximum in other hard type II superconductors, CeRu2 samples exhibit two distinct peak features in their FP-H plots. Our results show that the scaling of FP with the applied magnetic field at different temperatures cannot be described by the conventional Kramer model based on crossover from a line-breaking regime to a flux-line lattice shearing regime.
