超导结的约瑟夫森电流可以被外场调制。约瑟夫森电流的这种调制通常通过施加磁场的一维扫描来观察。本文利用两对亥姆霍兹线圈，对外磁场H进行了二维扫描，首次测量了I/subc/-H关系的二维面。还研究了Fiske阶跃对电流-电压特性的调制作用。
Josephson current of superconducting junctions can be modulated by an external field. This modulation of the Josephson current I/sub c/ 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 I/sub c/-H dependence are first measured. Modulations of Fiske steps of the current-voltage characteristics are also studied.
