| Abstract(in English) | Modulation of current-voltage characteristics of niobium junctions by two-dimensional scan of the external magnetic field has been measured. Josephson current of superconducting junction can be modulated by applying an external magnetic field. From this modulation pattern of the Josephson current, the information of the uniformity of the tunnel barrier can be obtained. The modulation of the Josephson current I_c of the superconducting junctions is usually observed by one-dimensional scan of the applied magnetic field. In this article, by using two pairs of the Helmholz coils, the external magnetic field H to the junction is scanned in two dimensions, and the dependence on magnetic field of the DC Josephson currents of Nb/Al-oxide /Nb single and double junction structures have been observed. |
