摘要/Abstract

摘要： Current－voltage characteristics of the surface intrinsic Josephson junctions under a magnetic field parallel to CuO_2 planes have been studied experimentally. Fiske steps in such a junction have been observed. The Swihart velocity for the junction is found to be 7.2×10^5m/s, which corresponds to the velocity mode of a single junction.

Abstract: Current－voltage characteristics of the surface intrinsic Josephson junctions under a magnetic field parallel to CuO$_2$ planes have been studied experimentally. Fiske steps in such a junction have been observed. The Swihart velocity for the junction is found to be $7.2\times10^5$m/s, which corresponds to the velocity mode of a single junction.
