Robustness of the transition against compositional and structural ageing in S/F/S heterostructures
R. Loria, C. Meneghini, K. Torokhtii +5
We have studied the temperature induced thermodynamic transition in Nb/PdNi/Nb Superconductor/Ferromagnetic/Superconductor (SFS) heterostructures by microwave measurements o…
Nonlinear current-voltage characteristics due to quantum tunneling of phase slips in superconducting Nb nanowire networks
M. Trezza, C. Cirillo, P. Sabatino +3
We report on the transport properties of an array of N about 30 interconnected Nb nanowires, grown by sputtering on robust porous Si substrates. The analyzed system exhibits a broa…
Superconducting and structural properties of Nb/PdNi/Nb trilayers
N. Pompeo, K. Torokhtii, C. Meneghini +7
The superconducting and structural properties of S/F/S (Superconductor/Ferromagnet/Superconductor) heterostructures have been studied by means of microwave measurements (1-20 GHz)…
Microwave properties of Nb/PdNi/Nb trilayers. Observation of flux flow in excess of Bardeen-Stephen theory
K. Torokhtii, N. Pompeo, C. Meneghini +5
We combine wideband (1-20 GHz) Corbino disk and dielectric resonator (8.2 GHz) techniques to study the microwave properties in Nb/PdNi/Nb trilayers, grown by UHV dc magnetron sputt…
Quantum phase slips in superconducting Nb nanowire networks deposited on self-assembled Si templates
C. Cirillo, M. Trezza, F. Chiarella +4
Robust porous silicon substrates were employed for generating interconnected networks of superconducting ultrathin Nb nanowires. Scanning electron microscopy analysis was performed…
Vortex motion in Nb/PdNi/Nb trilayers: new aspects in the flux flow state
K. Torokhtii, C. Attanasio, C. Cirillo +4
We study the dynamics of vortex lines in Supercondutor/Ferromagnet/Superconductor (SFS) heterostructures at microwave frequencies. We have employed swept-frequency, Corbino-disk an…
