Magneto-microwave absorption observation of vortex creep-to-flow transitions in thin films of Tl2Ba2Ca2Cu3Ox

The temperature dependence of the microwave absorption due to a constant magnetic field in thin films of Tl2Ba2Ca2Cu3Ox on single-crystal MgO substrates shows two temperature regions between 77 K and 120 K in which the absorption has a different dependence on temperature. The temperature at which the crossover occurs depends on the magnetic field, increasing as the field decreases, and is identified as the temperature at which the vortices become depinned and undergo flux flow. A measurement of the transition temperature versus magnetic field allows a determination of the irreversibility line for the film.
