Abstract
Thermally excited fluxoids are found in the resistive region of the superconducting transition of thin aluminum films withR ▭=10 Ω by a method using a dc transformer. TheR(T) andI–V dependences obtained atT→T 2D correspond to the universal relations of the theory of a Berezinskii-Kosterlitz-Thouless phase transition. The observed effects are related to the presence of a two-dimensional system of Josephson weak links in the films and the dissipative dynamics of the fluxoids in such structures.
