We present experimental results concerning both the fabrication and the characterization of superconducting tunnel junctions based on Nb/NiCu superconductor/ferromagnet (S/F) bilayers. Josephson junctions have been characterized down to T=1.4 K in te

Recent findings by G.Pepe et al. (Appl.Phys.Lett.89, 2770, 2001) have given new insights over the dynamics of Josephson junctions subject to electronic pulse injection. These experiments can be considered important steps toward the study of non-equil

We report on femtosecond optical pump-probe studies of proximized ferromagnet/superconductor (F/S) hybrids, consisting of Ni0.5Cu0.5 layers deposited on top of Nb films. The weak ferromagnetic nature of the completely proximised Ni0.5Cu0.5 film makes

Superconductors are highly suitable materials for radiation detection. Several detector types have been proposed, with properties of fast detection or high wavelength resolution over a wide range of optical frequencies. Their performances depend on t

We have recorded the radiation generated by magnetic flux quanta oscillations and by cavity mode oscillations in two-stacked arrays each consisting of five long Josephson junctions biased in parallel. The two arrays have in common the middle electrod

We consider a structure consisting of two parallel arrays of long Josephson junctions sharing a common electrode that allows inductive coupling between the arrays. Cavity modes excitations exhibiting 2D synchronization as well as solitonic excitation

We have addressed the problem of the phase-locking mechanism of a single Josephson junction irradiated with microwaves, and have numerically and theoretically explored the possibility to achieve ac gain in this system. By investigating the capability

We ropose a Structure where homopolar fluxons are expected to have an attractive interaction energy on a physically intuitive basis and such an interaction is recovered in the proposed mathematical model of the system. The inferred coherent motion of

Double-barrier Nb/AlOx /Al/AlOx /Nb devices were fabricated and investigated in direct-current and alternating-current (ac) electromagnetic fields. The occurrence of current singularities and of the ac Josephson effect at T = 4.2 K are demonstrated.

Decay of a zero-voltage state of a Josephson junction at low temperature occurs via quantum tunneling through an effective potential barrier. An extremely small probability of quantum tunneling may become not very small under the action of an ac comp
