UniSa - IRIS Institutional Research Information System
IRIS è la soluzione IT che facilita la raccolta e la gestione dei dati relativi alle attività e ai prodotti della ricerca. Fornisce a ricercatori, amministratori e valutatori gli strumenti per monitorare i risultati della ricerca, aumentarne la visibilità e allocare in modo efficace le risorse disponibili.
EnglishIn several superconducting applications, low energy losses are strictly demanding. In superconducting films, the dissipative flux flow state plays a role in the stability of the superconducting state in those devices that can operate just above the critical current (Ic). Therefore, details of the current-voltage (I-V) characteristics and in particular of current instabilities from the flux flow state to the normal one can become significant. We study current stability in the flux flow dissipative state by a proper current-voltage measurement mode. Low-temperature superconducting films have been investigated to demonstrate that the current stability range above I c can be increased by light ion irradiation. © 2002-2011 IEEE.
