Mg. Forrester et al., A SINGLE FLUX QUANTUM SHIFT REGISTER OPERATING AT 65 K, IEEE transactions on applied superconductivity, 5(2), 1995, pp. 3401-3404
We report the fabrication and quasi-static testing of a two-stage, hig
h-temperature superconducting, Single Flux Quantum shift register. The
five-junction circuit was fabricated using a single YBCO film, with s
tep-edge grain boundary junctions. Storage of flux, and its motion in
response to LOAD and SHIFT signals, was demonstrated at 65 K.
