Abstract
Microwave surface resistance measurement constitutes one of the most advantageous procedures for the investigation and characterization of the new superconducting oxides. Keeping in mind that the bulk ceramic materials usually have cylindrical symmetry, a new automatic measuring system, based on a resonant cavity, has been developed with special emphasis on superconducting pellets. The resolution capability of our system is pointed out by measuring the surface resistance of YBCO and BSCCO samples.
