    Abstract

    Upper-critical-field results on disordered thin-film superconducting La-S films are presented. A striking anisotropy in Hc2 is observed with different field orientations. This critical-field anisotropy reflects the geometry of the superconducting paths in the films. The qualitative behavior of Hc2 as a function of temperature and film resistivity can be understood within a percolation model.
