We fabricated YBa2Cu3O7-x (YBCO) nanobridges with an asymmetric structure, which were expected to show asymmetric current-voltage characteristics, aiming to the application for superconducting rectifying devices, and investigated their properties. The asymmetric nanobridges showed asymmetric current-voltage characteristics in an external magnetic field. The critical currents varied by about 10 percent at 2.4 mT. We also observed thedecrease in the critical current for the positive current direction with varying magnetic field from –2.5 mT to +2.5 mT, while the critical current for the negative direction increased. These characteristics suggested the ratchet-like behavior of vortices in the nanobridge, which reflected the shape effect. We also obtained the magnetic field dependence of the dynamic resistance near Ic, which would suggest the change of the vortex behavior by the magnetic field. |
