N2 - Utilizing phenomenological two-components Ginzburg-Landau equation, we investigate the vortex structures in nano-sized composite structures of d- and s-wave superconductors (d-dot), which shows spontaneous half-quantum magnetic fluxes. Especially, effects of disorders in junctions between d- and s-wave superconductors are investigated. Holes in junction at the corners do not affect the magnetic flux patterns. Although the large hole at the corner changes the position of the flux. A wide disorder along the junction affects the magnetic structures much. At the edges of the non-disordered junction, there appear fractional fluxes.
