MIXED-STATE AND CRITICAL-CURRENT IN NARROW SEMICONDUCTING-FILMS

The mixed state of thin narrow superconducting films with an edge barr ier placed in a transverse magnetic field is considered. The boundarie s of the region for the existence of metastable mixed states with an a ssigned number of vortices N [H-min(N)less than or equal to H less tha n or equal to H-max(N)] are found. The magnetic-field dependence of th e critical field is found for the films. The transition from the Meiss ner state to the static mixed state is discussed. (C) 1998 American In stitute of Physics.
