Abstract
Applying the finite element method to the Ginzburg-Landau equation, we developed a numerical method that calculated superconducting states and magnetic field distributions for the composite structures of the high-Tc superconductor and the conventional superconductor in arbitrary geometries. We show spontaneous magnetic flux appears at the corner of the boundary of these two superconductors. Also we propose high-Tc superconducting dot embedded in conventional superconductors, which is named as d-dot, and show the spatial distribution of superconducting order parameters and the magnetic field for several d-dots.
