A transmission method in microwave frequencies was found that would allow the study of the magnetic properties of type II superconductors in bulk. The thick crystalline samples of YBa2Cu3O7-x form the common wall between two microwave cavities operating in the x-band. The Abrikosov or mixed state is induced by an externally applied magnetic field applied along the c-axis of the sample. One cavity is used for the excitation of vortices and the other to detect the transmitted signal. The field dependence of the transmitted signal below the superconducting transition temperature is consistent with vortex formation. It is hoped that this method can contribute to further detailed study of vortex dynamics and lattice structure.
