PROPERTIES OF VORTEX SYSTEM WITH RANDOM COLUMNAR DEFECTS AT ZERO TEMPERATURE |
| |
| Abstract: | The properties of a two\|dimensional vortex system with random columnar defects were studied by cooling the vortex system to zero temperature. The vortex lattice became more and more disordered with increasing pinning strength \%f\-p\%. At small \%f\-p\%, a triangular vortex lattice away from the pins was observed. The peak of structure factor \%S(G\-0)\% of the vortex lattice decreased with pinning strength \%f\-p\%, which accorded with the finding that the probability of vortex to be pinned increased with \%f\-p\%. Some of our results agreed with experimental findings. |
