Superconducting Proximity Effects and Josephson Coupling in CoFeB Structures
… and logic devices. Following a review of the current field and an initial materials characterisation, CoFeB is assessed alongside the superconductor niobium (Nb) in two archetypal superconducting spintronic devices. The first of these is the superconducting spin-valve, in which a modification …

Sources of noise in niobium-based superconducting quantum circuits
… materials are thought to cause changes to the Josephson critical current or the flux through the superconducting loop of a flux qubit, which leads to decoherence in the qubit. Alternatively, defects in the crystal lattice give rise to electron localization which in turn traps spins with random …

Josephson Junctions and Devices fabricated by Focused Electron Beam Irradiation
… (STEM), can result in the formation of a Josephson junction. The conditions required for the formation of these Josephson junctions in YBa2Cu3O7-d and related compounds are discussed as well as the physical properties of the irradiated material. From electrical transport measurements of …

Superconducting Transition-Edge Sensor Physics
… T and magnetic field B dependence of the critical current Ic measured over 7 orders of magnitude on square Mo/Au bilayers ranging in length from 8 to 290 microns. We find our measurements have a natural explanation in terms of a spatially varying order parameter that is enhanced in …
