CINECA 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.
EnglishPerpendicular nanomagnets can host complex bubble-like dynamics driven by the localized injection of a spinpolarized current. This kind of dynamics is here fully analyzed, by means of micromagnetic simulations, in two typical spintronic geometries: confined point-contact spin-valve and extended nanocontact oscillator. The multi-approach analysis gets information from the time domain signal, its frequency spectrum, the magnetization configuration, the spatial mode distribution and the wavelet analysis.
