摘要：

In the present paper, we study the effect of the boundary conditions (deGennes-parameter b) on the magnetization (M), critical fields (H1,H2), and Cooper pair density (|W|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 0) configurations, such as the side through which the magnetic flux enters the sample.
