  • Abstract
    Josephson current of superconducting junctions can be modulated by an external field. This modulation of the Josephson current Ic is usually observed by one-dimensional scan of the applied magnetic field. In this paper, using two pairs of the Helmholz coils, the external magnetic field H is scanned in two dimensions and the two-dimensional surfaces of the Ic-H dependence are first measured. Modulations of Fiske steps of the current-voltage characteristics are also studied
