TL;DR: In this paper, the presence of energy levels quantization in high quality underdamped Josephson junctions at temperatures above the quantum crossover temperature was observed and it was shown that the escape rate out of the zero-voltage state at higher sweeping frequency (up to 25 A/sec) can induce nonstationary conditions in the energy potential describing the junction dynamics.

TL;DR: An integrated magnetic nanosensor based on a niobium dc SQUID (superconducting quantum interference device) for nanoscale applications is presented and possible applications can be envisaged in magnetic detection of nanoparticles and small clusters of atoms and molecules, in the measurement of nanoobject magnetization and in quantum computing.

TL;DR: In this article, two multichannel systems based on a superconducting quantum interference device (SQUID) for biomagnetic measurements, installed at the University of Chieti, are presented.

TL;DR: In this paper, the spontaneous zero-field currents in superconducting networks of temperature-controlled π-junctions with weakly ferromagnetic barriers have been observed and the onset of spontaneous supercurrents at the 0-π transition temperature of the junctions, Tπ≈3 K.

TL;DR: In this article, a reliable procedure based on the niobium technology has been developed to fabricate low intrinsic noise Josephson devices, which well meet the requirements of multichannel systems for biomagnetic measurements.
