Abstract

We have studied SmBa₂Cu₃O_y (Sm123) thin films fabricated by low temperature growth (LTG) technique. The critical current densities (J_cs) in magnetic fields at 77 K of the LTG-Sm123 film embedded nanosized low-T_c particles (NLP) were comparable to that of NbTi wire at 4.2 K. Furthermore, at low temperatures of 65 and 40 K, the J_c-B curves of the LTG-Sm123 film were superior to even that of Nb₃Sn wire at 4.2 K and the anomalous peaks were observed on the J_c-B and F_p-B curves. Based on the scaling of the flux pinning force, we found that fluxes in the film would be pinned at grain boundary mainly and the anomalous peaks were caused by the NLP.
