摘要：

Three-terminal double-junction Nb/Al-AlO(x)-Nb/Al-AlO(x)-Nb tunnel devices with a thin (almost-equal-to 13 nm) Nb/Al middle layer have been investigated. Strong interaction between the two junctions has been observed, as a result at zero voltage the system can behave like a single junction with one critical current. This state is stable and can be characterized by identical phase distributions for the two junctions. At some value of the applied magnetic field, a transition to another state occurs, in which the individual junctions behave relatively independently.
