抄録

HoBa2Cu3Oy (HoBCO) films on the bi-axially textured buffer layer prepared by Inclined Substrate Deposition method are studied. The HoBCO and buffer layers are supported by Ni-based-alloy substrate to form superconducting tape. Critical current density (Jc) of this tape exceeds about 1 × 109 A/m2 at 77 K in the self-field. To investigate practical performance of this tape, various dependences of Jc, such as the magnetic-field dependence is measured. For the measurement of Jc in the magnetic field, its dependence of the angle of the field and the tape's plane is taken into account. The result shows that Jc has a notable peak when the magnetic field is perpendicular to the angle of the field to the tape's plane. The Jc peak gradually diminishes as the field increases. Similar magnetic field dependence of Jc is observed in a YBa2Cu3Oy (YBCO) sample. This study confirms that data of the perpendicular and parallel field dependence of Jc, as such, are not sufficient for evaluation of practical performance of HoBCO tape.
