摘要：

We have synthesized the filamentary LRE (LRE=Nd, Sm, Eu, Gd)123 superconductors by solution spinning and melt growth process in flowing 1%O-2+Ar (OCMG). The effect of heating condition for oxygenation on the field dependence of Je at 77K of the filamentary (Nd, Sm, Eu, Gd)123 superconductors was examined. High Je value of 6100 A/cm(2) at 77 K and 9 T was measured by controlling the heating condition. The T-c of the sample was 95 K with DeltaT(c)=1.5 K. The pinning properties of the sample were examined by extended analysis of volume pinning force and it was found that Delta kappa -point pinning was dominant in this case.
