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…
Josephson effects in MgB2 meta masked ion damage junctions
D. -J. Kang, N. H. Peng, R. Webb +8
Ion beam damage combined with nanoscale focused ion beam direct milling was used to create manufacturable SNS type Josephson junctions in 100 nm thick MgB with T of 38…
A Directly Coupled Superconducting Quantum Interference Device Magnetometer Fabricated in Magnesium Diboride by Focused Ion Beam
G. Burnell, D. -J. Kang, D. A. Ansell +4
We report the fabrication of a directly coupled superconducting quantum interference device (SQUID) magnetometer in MgB2 using a focused ion beam (FIB) to create Josephson junction…
Novel Josephson Junction Geometries in NbCu bilayers fabricated by Focused Ion Beam Microscope
R. H. Hadfield, G. Burnell, P. K. Grimes +2
We explore novel junction configurations as an extension of our established Focused Ion Beam-based low TC SNS Junction fabrication technique. By milling a circular trench (diameter…
Planar Superconductor-Normal-Superconductor Josephson Junctions in MgB2
G. Burnell, D. -J. Kang, H. N. Lee +3
Since the discovery of superconductivity in MgB2 considerable progress has been made in determining the physical properties of the material, which are promising for bulk conductors…
