Controllable Josephson current through a pseudo-spin-valve structure
C. Bell, G. Burnell, C. W. Leung +3
A thin Co/Cu/Permalloy (NiFe) pseudo-spin-valve structure is sandwiched between superconducting Nb contacts. When the current is passed perpendicular to the plane of…
Proximity and Josephson effects in superconductor - antiferromagnetic Nb / γ-Fe50Mn50 heterostructures
C. Bell, E. J. Tarte, G. Burnell +3
We study the proximity effect in superconductor (S), antiferromagnetic (AF) bilayers, and report the fabrication and measurement of the first trilayer S/AF/S Josephson junctions. T…
Disorder induced collapse of the electron phonon coupling in MgB observed by Raman Spectroscopy
K. A. Yates, G. Burnell, N. A. Stelmashenko +4
The Raman spectrum of the superconductor MgB has been measured as a function of the Tc of the film. A striking correlation is observed between the onset and the frequ…
Decoupling of a Current-Biased Intrinsic Josephson Junction from its Environment
P. A. Warburton, A. R. Kuzhakhmetov, G. Burnell +2
We have observed a dissipative phase diffusion branch in arrays of hysteretic high-Tc intrinsic Josephson junctions. By comparing the data with a thermal activation model we extrac…
The critical current of YBa2Cu3O7-d Low Angle Grain Boundaries
J. H. Durrell, M. J. Hogg, F. Kahlmann +3
Transport critical current measurements have been performed on 5 degree [001]-tilt thin film YBa2Cu3O7-delta single grain boundaries with magnetic field rotated in the plane of the…
