    Abstract

    We have reported novel PVD and MOCVD growth technique, "vapor-liquid-solid growth" and "low-temperature growth (LTG) technique", for the high superconducting properties and high growth rate. Recently the Jc value can be improved by an artificial pinning center (APC) in REBCO film and coated conductor at a magnetic field. Using LTG technique, high Jc-SmBCO thick layer and coated conductor in a magnetic field were fabricated with high quality SmBCO-thin seed layer on single crystalline substrate and metal tape. From the surface morphologies and micro structure, we found that LTG is an effective technique for increasing the dislocations without deteriorating crystallinity or superconducting properties. We conclude the dislocations grown at low substrate temperature are effective pinning center in a magnetic field. Furthermore we studied about the crystal growth and pinning mechanism of (Nd/Eu/Gd)BCO films and coated conductor grown by LTG technique for high Jc in magnetic fields. In addition SmBCO films with nano-BaZrO3 (BZO) were grown by LTG technique, because BZO rods in PLD-YBCO films have been investigated for flux pinning.
