Hybrid nanostructures not only open new routes for studying the coexistence of superconductivity and ferromagnetism, but they also provide new insights into the fundamentals of quantum electronics. We have investigated, by a series of experiments, th

Phase sensitive experiments have shown that the gap function of HTC superconductors changes of sign in the way expected for a condensate wave function with d x 2 − y 2 symmetry suggesting unconventional pairing. We present tunneling spectroscopy, J

We report transport measurements on Superconductor/Ferromagnet/Superconductor (S/F/S) junctions: Nb/Al/Gd/Al/Nb where gadolinium (Gd) is a weakly polarized ferromagnet. A sizeable critical current I c is observed in the I(V) characteristics. This cur

We review the mesoscopic transport in a diffusive proximity superconductor made of a normal metal (N) in metallic contact with a superconductor (S). The Andreev reflection of electrons on the N-S interface is responsible for the diffusion of electron

A new method for measuring heat capacities that makes the calibration of thermometers obsolete is presented. The particularity of the principle, based on the ac steady-state method, is the insertion of a reference mass with a heater between the ensem

An innovative nanocalorimeter has been developed for measuring specific heats of thin films, multilayers (typical thickness: 1000 A) and single crystals (mass: 1 μg) in the temperature range of 1.5–20 K. The addenda of the device are as small as 3

A particularly sensitive heat capacity measuring device has allowed us to measure the tunneling process of ${\mathrm{Mn}}_{12}{\mathrm{O}}_{12}$-acetate single crystals (mass: $1$ and $20\ensuremath{\mu}\mathrm{g}$) from the irreversible tunneling pr

A microcalorimetry technique allowing one to measure the specific heat of bulk single crystals of a mass typically 10 μg, with a relative resolution Δc/c of 10−4 is presented. The well known ac steady state technique is employed. The sample holde

We introduce a calorimetric approach to probe persistent currents in normal metal rings. The heat capacity of a large ensemble of silver rings is measured by nanocalorimetry under a varying magnetic field at different temperatures (60, 100, and 150 m
