Critical temperature oscillations in magnetically coupled superconducting mesoscopic loops
M. Morelle, V. Bruyndoncx, R. Jonckheere +1
We study the magnetic interaction between two superconducting concentric mesoscopic Al loops, close to the superconducting/normal phase transition. The phase boundary is measured r…
Superconductivity in a Mesoscopic Double Square Loop: Effect of Imperfections
V. M. Fomin, J. T. Devreese, V. Bruyndoncx +1
We have generalized the network approach to include the effects of short-range imperfections in order to analyze recent experiments on mesoscopic superconducting double loops. The…
Nucleation of Superconductivity in a Mesoscopic Loop of Finite Width
V. Bruyndoncx, L. Van Look, V. V. Moshchalkov
The normal/superconducting phase boundary Tc has been calculated for mesoscopic loops, as a function of an applied perpendicular magnetic field H. While for thin-wire loops and fil…
Dimensional crossover in a mesoscopic superconducting loop of finite width
V. Bruyndoncx, L. Van Look, M. Verschuere +1
Superconducting structures with the size of the order of the superconducting coherence length xi(T) have a critical temperature T_c, oscillating as a function of the applied perpen…
Giant vortex state in perforated aluminum microsquares
V. Bruyndoncx, J. G. Rodrigo, T. Puig +3
We investigate the nucleation of superconductivity in a uniform perpendicular magnetic field H in aluminum microsquares containing a few (2 and 4) submicron holes (antidots). The n…
Confinement and Quantization Effects in Mesoscopic Superconducting Structures
V. V. Moshchalkov, V. Bruyndoncx, E. Rosseel +6
We have studied quantization and confinement effects in nanostructured superconductors. Three different types of nanostructured samples were investigated: individual structures (li…
