FIG. 1.

Schematic of the fabricated YBCO ring-shaped thin film integrated with two stacks of the -axis intrinsic Josephson junctions (see text). The arrows show the flow of the circulating persistent current.

FIG. 2.

(a) The profile of the axial field (measured at ) generated by the -axis critical persistent current (middle curve), the bulk vortices (bottom curve), and the combined field of both (top curve). (b) The profile of the axial self-field induced by the -axis critical persistent current. The solid line is the self-field of the circulating current calculated from the Biot–Savart’s law. (c) Temperature dependence of the self-field of the -axis critical persistent current.

Image of FIG. 3.
FIG. 3.

The temperature dependence of the -axis critical current [ ] (solid spheres) showing a clear deviation from the Ambeagokar–Baratoff dependence (dashed curve).

Image of FIG. 4.
FIG. 4.

(a) The temperature dependence of the resistance of the IJJ and the bulk film. The inset shows the magnified region close to . (b) characteristics of the stack of the IJJs at . The thick solid curve shows the dependence of the tunneling current on the bias voltage across the junction. The thin solid curve is the dependence of the voltage across the junctions as a function of the bias current. The insets show the temperature dependence of the gap voltage of the IJJs as well as the schematic of the configuration of the electrical contacts.
