| Abstract: | We fabricated step-edge Josephson junctions of YBa2Cu3O7−d
on MgO substrates by a pulsed laser deposition method for high frequency applications. On the basis of temperature dependence
of critical current, noticeable deterioration has not been observed in a step-edge area. The dynamic resistance was between
2 and 3Ω under the superconducting critical temperature. A deviation from a resistively shunted junction model was observed,
which implies the excess current not flowing through Josephson junctions. |
