    Abstract

    Current-voltage (I-V) curves of step-edge YBa2Cu3Oy junctions SQUIDs and Junctions in parallel in a magnetic field and under microwave irradiation were measured. IC- curves for a single Josephson junctions show Fraunhofer diffraction pattern. The voltage of SQUIDs and Josephson 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 irradiation in bi-epitaxial SQUIDs. The noninteger voltage steps can be modulated by the microwave power and the applied magnetic field.
