Abstract

The precondition for the Berezinskii-Kosterlitz-Thouless (BKT) transition in thin superconducting films, i.e., the logarithmic intervortex interaction, is satisfied at short distances relative to Lambda=2 lambda(2)/d, where lambda is the London penetration depth of the bulk material and d is the film thickness. For this reason, the search for the transition has been conducted in samples of the size L
