Abstract

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. 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 Helmholtz 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.
