Recent scientific activity

Non-linear dissipations in the I-V characteristic of type-II superconductors (HTS, LTS, IBS) to identify the magnetic field-temperature (H-T) phase diagram, the presence of order-disorder transitions in the Abrikosov vortex lattice induced by a bias current, the pinning influence on vortex lattice dynamics.

Electrical transport measurements as a function of temperature and magnetic field intensity and orientation, in the limit of high current and dissipation, to investigate the Abrikosov vortex dynamics at high speed. Quenching currents in materials useful for coated conductors in large-scale applications and in materials useful for photon detection.
