Direct observation of vortices in an array of holes at low temperature: temperature dependance and first visualization of localized superconductivity
Cecile Veauvy, Klaus Hasselbach, Dominique Mailly
A scanning micro superconducting quantum interference device (microSQUID) microscope is used to directly image vortices in a superconducting Al thin film. We observe the temperatur…

Direct measurement of the phase coherence length in a GaAs/GaAlAs square network
Meydi Ferrier, Lionel Angers, Sophie Gueron +5
The low temperature magnetoconductance of a large array of quantum coherentloops exhibits Altshuler-Aronov-Spivak oscillations which periodicitycorresponds to 1/2 flux quantum per…
