Abstract
The influence of doping the Laves-phase superconductor CeRu2 with La is studied by resistivity and magnetization measurements. As the La concentration increases the electronic mean free path and the spin susceptibility decrease. These changes modify the pinning properties of the vortex lattice, especially the peak effect. Although the magnetic field, at which the vortex lattice undergoes a crossover from weak to strong pinning, is increased, the pinning potential itself is not affected by the impurities.
