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…
Superconducting nanowire quantum interference device based on Nb ultrathin films deposited on self-assembled porous Si templates
C. Cirillo, S. L. Prischepa, M. Trezza +2
Magnetoresistance oscillations were observed on networks of superconducting ultrathin Nb nanowires presenting evidences of either thermal or quantum activated phase slips. The magn…
Thermodynamic nature of the 0-PI quantum transition in superconductor-ferromagnet-superconductor trilayers
N. Pompeo, K. Torokhtii, C. Cirillo +5
In structures made up of alternating superconducting and ferromagnet layers (S/F/S heterostructures), it is known that the macroscopic quantum wavefunction of the ground state chan…
Local characterization of ferromagnetic properties in ferromagnet/superconductor bilayer by Point Contact Andreev Reflection Spectroscopy
Filippo Giubileo, Francesco Romeo, Roberta Citro +5
We realized point contact spectroscopy experiment on ferromagnet/superconductor bilayers. Differential conductance curves show several features that we explained within Bogoliubov-…
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)…
