Josephson Junctions Via Anodization of Epitaxial Al on an InAs Heterostructure
A. Jouan, J. D. S. Witt, G. C. Gardner +5
We combine electron beam lithography and masked anodization of epitaxial aluminium to define tunnel junctions via selective oxidation, alleviating the need for wet-etch processing…
Control of superconductivity with a single ferromagnetic layer in niobium/erbium bilayers
N. Satchell, J. D. S. Witt, M. G. Flokstra +5
Superconducting spintronics in hybrid superconductor/ferromagnet (S-F) heterostructures provides an exciting potential new class of device. The prototypical super-spintronic device…
Supra-oscillatory critical temperature dependence of Nb-Ho bilayers
F. Chiodi, J. D. S. Witt, R. G. J. Smits +7
We investigate the critical temperature Tc of a thin s-wave superconductor (Nb) proximity coupled to a helical rare earth ferromagnet (Ho). As a function of the Ho layer thickness,…
