摘要：
Niobium dc SQUIDs based on ferromagnetic Josephson junctions were proposed. The phase difference of the junctions within the SQUID was fixed by the ferromagnetic layer thickness. SQUIDs with π junction show a half quantum flux shift in the diffraction pattern. Ferromagnetic π junctions could be easily implemented as a π shifter in superconducting networks and devices.
