Effects of edge boundaries on Josephson vortices in finite-size layered High-Tc superconductors -: art. no. 097002

In order to systematically explain the in-plane size effects for the periodical dependence of the Josephson-vortex-flow resistance on the magnetic field, we numerically explore static lattice structures of Josephson vortices in layered high-T-c superconductors with finite in-plane sizes from sub-mu m to more than 10 mu m by simulating slow quenching processes from high temperature under the magnetic field. The numerical results reveal that in sub-mu m size the rectangular lattice is a widely spread major structure in H-T diagram and the triangular lattice is a minor one which emerges only around the specific magnetic field supplying n phi(0) per one junction area. These results suggest that sub-mu m size layered high-T-c superconductors are promising for future device applications.
