摘要
In this study, the angular dependence of J(c) is investigated in detail for YBa2Cu3Oy (YBCO) tape fabricated by the inclined substrate deposition method. The result shows that J(c) has a notable peak when the magnetic field is perpendicular to the plane of the tape, which indicates that the tape has lower J(c) at medium degrees of the angle of the field to the tape's plane. The peak gradually diminishes as the field increases. This study confirms that data of the perpendicular and the parallel field dependence of J(c), as such, are not sufficient for evaluation of practical performance of YBCO tape.
