Abstract |
YBaCuO superconducting ceramic thick films were fabricated by chemical process. YBaCuO films have been successfully grown on SrTiO_3 substrates without a template layer. The films show poor or non superconductivity although they have excellent crystalline properties. ion channeling measurement made it clear that the strain in the films due to strong chemical bonding between the substrate and epilayer remains, resulting in the poor superconductivity. The X ray diffraction pattern of the YBaCuO thick films contained 90K phase. The self template method have resolved this problem. We obtained high-Jc as-grown YBaCuO on SrTiO_3 (100). |
