Competition between Superconductivity and Weak Localization in Metal-Mixed Ion-Implanted Polymers
Andrew P. Stephenson, Adam P. Micolich, Ujjual Divakar +2
We study the effects of varying the pre-implant film thickness and implant temperature on the electrical and superconducting properties of metal-mixed ion-implanted polymers. We sh…
Preparation of Metal Mixed Plastic Superconductors: Electrical Properties of Tin-Antimony Thin Films on Plastic Substrates
Andrew P. Stephenson, Ujjual Divakar, Adam P. Micolich +2
Metal mixed polymers are a cheap and effective way to produce flexible metals and superconductors. As part of an on-going effort to learn how to tune the properties of these system…
Direct observation of the flux-line vortex glass phase in a type II superconductor
U. Divakar, A. J. Drew, S. L. Lee +10
The order of the vortex state in La_{1.9} Sr_{0.1} CuO_{4} is probed using muon spin rotation and small-angle neutron scattering. A transition from a Bragg glass to a vortex glass…
Muons as Local Probes of Three-body Correlations in the Mixed State of Type-II Superconductors
G. I. Menon, A. Drew, U. K. Divakar +10
The vortex glass state formed by magnetic flux lines in a type-II superconductor is shown to possess non-trivial three-body correlations. While such correlations are usually diffic…
Field-induced hexagonal to square transition of the vortex lattice in overdoped La{1.8}Sr{0.2}CuO{4}
R. Gilardi, J. Mesot, A. J. Drew +6
We report on a small angle neutron scattering study of the vortex lattice in overdoped La{2-x}Sr{x}CuO{4} (x=0.2) up to high magnetic fields (9.5 Tesla) applied perpendicular to th…
A small angle neutron scattering study of the vortex matter in La{2-x}Sr{x}CuO{4} (x=0.17)
R. Gilardi, S. Streule, A. J. Drew +7
The magnetic phase diagram of slightly overdoped La{2-x}Sr{x}CuO{4} (x=0.17) is characterised by a field-induced hexagonal to square transition of the vortex lattice at low fields…
Direct evidence for an intrinsic square vortex lattice in the overdoped high-Tc superconductor La1.83Sr0.17CuO4+d
R. Gilardi, J. Mesot, A. Drew +10
We report here the first direct observations of a well ordered vortex lattice in the bulk of a La(2-x)Sr(x)CuO(4+d) (La214) single crystal (slightly overdoped, x=0.17). Our small a…
