Abstract
The complex ac impedance of c-axis YBa2Cu3O7-delta thin films is measu red as a function of temperature, driving frequency and magnetic field . The data exhibit a frequency dependent crossover from a liquid-like state of the vortices at high temperatures to a solid-like state at lo w temperatures.
