Sudden Critical Current Drops Induced in S/F Structures
E. J. Patino, C. Bell, M. G. Blamire
In the search for new physical properties of S/F structures, we have found that the superconductor critical current can be controlled by the domain state of the neighboring ferroma…
Critical Current Oscillations in Strong Ferromagnetic Pi-Junctions
J. W. A. Robinson, S. Piano, G. Burnell +2
We report magnetic and electrical measurements of Nb Josephson junctions with strongly ferromagnetic barriers of Co, Ni and Ni80Fe20 (Py). All these materials show multiple oscilla…
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…
