Dimensionality control and rotational symmetry breaking superconductivity in square-planar layered nickelates
Lin Er Chow, Km Rubi, King Yau Yip +11
The interplay between dimensionality and various phases of matter is a central inquiry in condensed matter physics. New phases are often discovered through spontaneously broken sym…
Pauli-limit violation in lanthanide infinite-layer nickelate superconductors
L. E. Chow, K. Y. Yip, M. Pierre +15
Superconductivity can be destroyed by a magnetic field with an upper bound known as the Pauli-limit in spin-singlet superconductors. Almost all the discovered superconductors are s…
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)…
