Fabrication and Characteristic of -123 Coated Conductors

. Sample with 1.3 in thickness of superconducting layer showed Jc (77.3 K, self field) was 1.8 near 2 and Ic (77.3 K, self field) was 231 A/cm-width. SEM photograph of Ho-123 layer revealed relatively smooth film morphology with some particles. This demonstrated fine epitaxial Ho-123 growth on textured Ni-alloy tape. Furthermore, Jc-B characteristics at 4.2 K under the high magnetic field up to 30 T were evaluated. Ic (4.2 K, 30 T) was over 2,000 A/cm-width when the external magnetic field was applied parallel to the tape surface.
