Loss of superconducting phase coherence in YBa(2)Cu(3)O(7) films: vortex-loop unbinding and Kosterlitz-Thouless phenomena.

ABSTRACT

The linear conductance G' + iG(") parallel to the CuO(2) planes of flat d = 50-600 nm thin films is measured between 30 mHz and 800 kHz. The decay of the phase-coherent superfluid density signals the proliferation of 3D vortex loops which terminates at T*
