Point-contact spectroscopy was originally developed for the determination of the electron– phonon spectral function in normal metals. However, in the past 20 years it has become an …

An overview of the theory of the upper critical field in dirty two-gap superconductors, with a particular emphasis on MgB2 is given. We focus here on the maximum Hc2 which may be …
Resonances in the superconducting properties, in a regime of crossover from BCS to mixed Bose-Fermi superconductivity, are investigated in a two-band superconductor where the …
We studied the influence of the disorder introduced in polycrystalline Mg B 2 samples by neutron irradiation. To circumvent self-shielding effects due to the strong interaction between …
This book presents the anisotropy and multiband effects in newly discovered unconventional superconductors: cuprate superconductors, borocarbides, magnezium-diboride and …
We report specific heat measurements on neutron-irradiated MgB 2 samples, for which the critical temperature is lowered to 8.7 K, but the superconducting transition remains extremely …

Single crystals of MgB2, with a size up to 1.5× 1× 0.1 mm3 and with a weight up to 230μg, have been grown from flux with a high-pressure cubic anvil technique. Investigations of the …
Nb 3 Sn thin films are fabricated by sequential sputtering followed by annealing at 850– 1200° C in vacuum. The effects of the annealing temperature and time on the formation of …
We show that the upper critical field in nanometer-sized Nb particles is governed by the changes in the effective Ginzburg-Landau coherence length occurring due to two competing …
