Abstract
We have studied the vortex dynamics in the PrFeAsO0.60F0.12 superconducting sample by dc magnetization and dynamic magnetization-relaxation rate (Q) measurements. The field dependence of the superconducting irreversible magnetization Ms reveals a second magnetization peak or fishtail effect. The large value of Q is an indication of moderate vortex motion and relatively weak pinning energy. Data analysis based on the generalized inversion scheme suggests that the vortex dynamics can be described by the collective pinning model. The temperature dependence of the critical current is consistent with the pinning due to the spatial variation in the mean free path near a lattice defect (
