Abstract

The cortex dynamics in a highly c-axis oriented epitaxial Tl₂Ba₂Ca₂Cu₃O_x (Tl-2223) thin-film has been investigated via time-relaxation of the zero-field cooled and remanent magnetization, for low (50 Oe) and moderate (500 Oe) applied magnetic fields below 15 K. A T-independent plateau has been found and explained in terms of quantum tunneling of 2D vortices in the CuO₂ planes. The influence of the field on the transition has been studied. A T²-dependence has been found, this being an evidence of strong ohmic dissipation.
