The effects of 2.5-MeV electron irradiation on the magnetic properties of single crystals of the Remeika series superconductor Ca3Rh4Sn13 were studied using high-frequency ac susceptometry, magnetization, and electrical transport. This low-pinning cubic stannide is an ideal system to examine the effects of a controlled nonmagnetic pointlike disorder. The measured Campbell penetration depth was used to extract the magnetic field dependence of the unrelaxed critical current density, jc(H).
