抄録

We have studied SmBa2Cu3Oy (Sm123) thin films fabricated by low temperature growth (LTG) technique. The critical current densities (Jcs) in magnetic fields at 77 K of the LTG-Sm123 film embedded nanosized low-Tc particles (NLP) were comparable to that of NbTi wire at 4.2 K. Furthermore, at low temperatures of 65 and 40 K, the Jc-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 Jc-B and Fp-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.
