Abstract

We have synthesized the filamentary LRE (LRE=Nd, Sm, Eu, Gd) 123 superconductors by solution spinning and melt growth process in flowing 1%O2+Ar (OCMG). The effect of heating condition for oxygenation on the field dependence of Jc at 77 K of the filamentary (Nd, Sm, Eu, Gd) 123 superconductors was examined. High Jc value of 6100 A/cm2 at 77 K and 9 T was measured by controlling the heating condition. The Tc of the sample was 95 K with ΔTc=1.5 K. The pinning properties of the sample were examined by extended analysis of volume pinning force and it was found that Δκ-point pinning was dominant in this case.
