Experiments on the Correlation Between the Flux Line Lattice and the Crystal Lattice in Superconducting Lead Films

Abstract

The properties of pure superconductors with a cubic structure depend on the crystal orientation /1,2,3/. Consequently the arrangement of normal domains in the mixed state or in the intermediate state should be correlated with the crystal lattice. This was predicted theoretically /4/ and demonstrated experimentally /5-9/. In the following, the effect of the crystal symmetry on the arrangement of vortices and normal lamellae in thin pure Pb-crystals will be reported.
