Abstract
Mesoscopic Li doped BSCCO fibres are synthesized by the electrospinning technology and the sequent sintering treatment. With the assistance of high resolution energy-dispersive x-ray spectroscopy detector in the Aberration-corrected transmission electron microscopy, we discovered hidden CuO grains and separated Bi-2212 phases, which is proved by the existence of fishtail effect in the magnetization loops. The electric measurement is fulfilled via four probe method with the help of focus ion beam operation. A non-trivial resistance behaviour appears, which can be attributed to its polycrystalline and superconducting phase separation features.
