High critical-current density of Y-Ba-Cu-O superconducting films prepared by CVD

Year: 1989

Type: article

Abstract: YBa 2 Cu 3 O 7-x films were prepared on SrTiO 3 (100) at 850 degrees C by chemical vapour deposition using beta -diketone metal chelate as source materials. The X-ray diffraction pattern of the YBa 2 Cu 3 O 7-x films showed distinct peaks of (001) with weak peaks of (h00). The superconducting transition temperature defined by zero resistivity was 91.5 K. Transport critical-current density at 77.3 K and 0 T was 2.0*10 6 A cm -2 .
