Abstract

The superconductive transition of c-axis-oriented ${YBa}_{2}$ ${Cu}_{3}$ $O_{7}$ thin films, as characterized by measurements of the temperature dependence of the magnetic penetration depth, is found to occur below the Ginzburg-Landau mean-field transition. The divergence of the penetration depth at the transition is in good quantitative agreement with the predictions of a percolation model.
