摘要

本文研究了边界条件（德根参数 b）对三维超导介边中的磁化（M）、临界磁场（H1,H2）和库珀对密度（|ψ|2）的影响，求解了与时间相关的金兹堡-朗道方程 TDGL。这些方程的求解考虑了退磁效应。我们的研究表明，超导介子楔的斜率可用于控制涡旋（磁通量Φ）的配置，例如磁通量从哪一侧进入样品。

Vortex state in a 3D superconducting mesoscopic wedge

In the present paper, we study the effect of the boundary conditions (deGennes-parameter $b$ ) on the magnetization (M), critical fields $(H_{1}, H_{2})$ , and Cooper pair density $({| ψ |}^{2})$ in a three-dimensional superconducting meso-wedge, solving the time-dependent Ginzburg–Landau equations $TDGL$ . These equations are solved by taking into account the demagnetization effects. We show that the slope of the superconducting meso-wedge can be used to control the vortex (fluxoids $Φ$ ) configurations, such as the side through which the magnetic flux enters the sample.

期刊介绍： Physica C (Superconductivity and its Applications) publishes peer-reviewed papers on novel developments in the field of superconductivity. Topics include discovery of new superconducting materials and elucidation of their mechanisms, physics of vortex matter, enhancement of critical properties of superconductors, identification of novel properties and processing methods that improve their performance and promote new routes to applications of superconductivity. The main goal of the journal is to publish: 1. Papers that substantially increase the understanding of the fundamental aspects and mechanisms of superconductivity and vortex matter through theoretical and experimental methods. 2. Papers that report on novel physical properties and processing of materials that substantially enhance their critical performance. 3. Papers that promote new or improved routes to applications of superconductivity and/or superconducting materials, and proof-of-concept novel proto-type superconducting devices. The editors of the journal will select papers that are well written and based on thorough research that provide truly novel insights.
