Abstract
We have fabricated epitaxial films of high-Jc SmBCO using a low-temperature growth technique (LTG). The angular dependence of Jc and composition analysis showed that the LTG-SmBCO films included nanosize low-Tc phases within the high-Tc matrix, the LTG-SmBCO films showed Jc = 0.28 MA/cm2 (77 K, B∥c, B = 5 T). However, number density of low-Tc phase is still less than the amount which is desired for complete flux-pinning at high-magnetic field. We deposited LTG-SmBCO including 1.4-2.8 vol.% of low-Tc nanoparticles. The films with 1.4 vol.% nanoparticles showed Jc = 0.37 MA/cm2 (77 K, B∥c, B = 5 T) and 0.10 MA/cm2 (77 K, B∥c, B = 8 T). We speculated that the behaviors of the Jc-B at high-magnetic field depend not only on distribution and size of low-Tc regions, but also the Sm/Ba composition within the low-Tc regions.
