Abstract

This 3-junction Josephson interferometer is comprised of two superconducting loops which are slightly mismatched in their LI(o) product. This mismatch is about 5%. This slightly asymmetric interferometer is very sensitive to small magnetic fields, and the shift in its threshold curve, due to an input magnetic signal, is a measure of the flux in that signal.
