Perpendicular 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.

Abstract
Perpendicular 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.File in questo prodotto:
