Abstract We study the superconducting state of a strip under an transport current J a and an external magnetic field H . We show that the value of the critical currents at which the vortex–antivortex (V–Av) pair penetrates the sample, the number of phase-slip lines, and their average velocities and dynamics strongly depend on the size of the sample L . Our investigation was carried out by numerically solving the two-dimensional generalized time-dependent Ginzburg–Landau equations (GTDGL).

超导带中相滑线数量的长度依赖性

摘要 我们研究了在输运电流J a 和外部磁场H 下带材的超导状态。我们表明，涡旋-反涡旋 (V-Av) 对穿透样品的临界电流值、相滑线的数量及其平均速度和动力学在很大程度上取决于样品 L 的大小。我们的研究是通过数值求解二维广义时间相关 Ginzburg-Landau 方程 (GTDGL) 来进行的。
