Magneto-transport of large CVD-grown graphene
Eric Whiteway, Victor Yu, Josianne Lefebvre +2
We present magnetoresistance measurements on large scale monolayer graphene grown by chemical vapor deposition (CVD) on copper. The graphene layer was transferred onto SiO2/Si via…
Cellulose-Bound Magnesium Diboride Superconductivity
Y. L. Lin, M. O. Pekguleryuz, J. Lefebvre +3
Two-phase superconductor tapes were produced by blending high purity magnesium diboride powder with a liquid ethylcellulose-based polymeric binder. This procedure produced a materi…
The strengthening of reentrant pinning by collective interactions in the peak effect
J. Lefebvre, M. Hilke, Z. Altounian
Since it was first observed about 40 years ago [1], the peak effect has been the subject of numerous research mainly impelled by the desire to determine its exact mechanisms. Despi…
Superconductivity and short range order in metallic glasses FeNiZr
J. Lefebvre, M. Hilke, Z. Altounian
In amorphous superconductors, superconducting and vortex pinning properties are strongly linked to the absence of long range order. Consequently, superconductivity and vortex phase…
Local magnetization fluctuations in superconducting glasses resolved by Hall sensors
J. Lefebvre, M. Hilke, Z. Altounian +2
We report on magnetization measurements performed on a series of FeNiZr superconducting metallic glasses with using the Hall effect of a nearby…
Transverse depinning in weakly-pinned vortices
J. Lefebvre, M. Hilke, Z. Altounian
We present experiments on weakly-pinned vortices, which exhibit a large critical transverse depinning force. These results are obtained in the superconducting metallic glasses Fe$_…
