Abstract
Current-voltage (I-V) curves of step-edge YBa2Cu3Oy junctions, SQUIDs, and Junctions in parallel in a magnetic field and under microwave irr adiation were measured. I-c-Phi curies for a single Josephson junction s show Fraunhofer diffraction pattern. The voltage of SQUIDs and Josep hson junctions in parallel at a constant bias current is modulated by external magnetic fields. In additional to integer Shapiro steps, non- integer constant-voltage steps were observed under microwave irradiati on in bi-epitaxial SQUIDs. The noninteger voltage steps can be modulat ed by the microwave power and the applied magnetic field.
