摘要：
In order to investigate the high frequency response of the vortex dynamics in high temperature superconducting thin films, we have developed a technique of measurement of the impedance of inverted microstrip lines in the broaband 5 MHz - 5 GHz, from 4.2 K to 100 K and from 0 to 7 teslas. Our results confirm a crossover in the frequency and field variation of the complex impedance. These results are compared with the modern theoretical model of Coffey-Clem (thermal activated flux flow).
