Pinning-induced formation of vortex clusters and giant vortices in mesoscopic superconducting disks
W. Escoffier, I. V. Grigorieva, V. R. Misko +4
Multi-quanta, or giant, vortices (GVs) are known to appear in very small superconductors near the superconducting transition due to strong confinement of magnetic flux. Here we pre…

Direct Observation of Vortex Shells and Magic Numbers in Mesoscopic Superconducting Disks
I. V. Grigorieva, L. Y. Vinnikov, W. Escoffier +4
We have visualised and studied vortex configurations in mesoscopic superconducting disks using the Bitter decoration technique. For a broad range of vorticities L the circular geom…

Anomalous proximity effect in an inhomogeneous disordered superconductor
W. Escoffier, C. Chapelier, N. Hadacek +1
By combining very low temperature scanning tunneling microscopy and spectroscopy on a TiN film we have observed a non uniform state comprising of superconducting (S) and normal (N)…
