    • Characteristics of strong ferromagnetic Josephson junctions with epitaxial barriers 

      Bell, Chris; Loloee, R.; Burnell, Gavin; Blamire, Mark G. (2005)
      We present the measurement of superconductor / ferromagnetic Josephson junctions, based on an epitaxial Nb bottom electrode and epitaxial Fe20Ni80 barrier. Uniform junctions have been fabricated with a barrier thicknesses ...
    • Nanoscale Josephson Devices 

      Bell, Chris (2003-12)
      This thesis describes the development and applications of sub-micron current-perpendicular-toplane devices fabricated by three-dimensional etching with a focused ion beam microscope. This technique was applied to a range ...
