Journal ArticleDOI
Direct observation of a propagating spin wave induced by spin-transfer torque
Marco Madami,Stefano Bonetti,Giancarlo Consolo,Silvia Tacchi,Giovanni Carlotti,Gianluca Gubbiotti,Fred Mancoff,Mazher Ahmed Yar,Johan Åkerman,Johan Åkerman +9 more
TL;DR: This work directly observes a propagating spin wave launched from a spin torque oscillator with a nanoscale electrical contact into an extended Permalloy (nickel iron) film through the spin transfer torque effect, and shows that spin waves with tunable frequencies can propagate for several micrometres.
Journal ArticleDOI

TL;DR: The Roadmap on Magnonics as mentioned in this paper is a collection of 22 sections written by leading experts in this field who review and discuss the current status but also present their vision of future perspectives.
Journal ArticleDOI
Brillouin light scattering studies of planar metallic magnonic crystals
Gianluca Gubbiotti,Silvia Tacchi,Marco Madami,Giovanni Carlotti,A. O. Adeyeye,Mikhail Kostylev +5 more
TL;DR: The application of Brillouin light scattering to the study of the spin-wave spectrum of one and two-dimensional planar magnonic crystals consisting of arrays of interacting stripes, dots and antidots is reviewed in this paper.
Journal ArticleDOI
Interfacial Dzyaloshinskii-Moriya Interaction in Pt/CoFeB Films: Effect of the Heavy-Metal Thickness.
Silvia Tacchi,Roberto E. Troncoso,Martina Ahlberg,Gianluca Gubbiotti,Marco Madami,Johan Åkerman,Johan Åkerman,P. Landeros +7 more
TL;DR: The observation of a Pt layer thickness dependence on the induced interfacial Dzyaloshinskii-Moriya interaction in ultrathin Pt(d_{Pt})/CoFeB films opens up a way to control and optimize chiral effects in ferromagnetic thin films through the thickness of the heavy-metal layer.
Journal ArticleDOI
Spin excitations of nanometric cylindrical dots in vortex and saturated magnetic states
Loris Giovannini,Federico Montoncello,F. Nizzoli,Gianluca Gubbiotti,Giovanni Carlotti,T. Okuno,Teruya Shinjo,M. Grimsditch +7 more
TL;DR: In this paper, the magnetic normal modes of nanometric magnetic disks are calculated using a recently developed, hybrid micromagnetic method based on the subdivision of a particle into small cells and the development of a ''dynamical matrix'' that contains the restoring torques acting on the magnetization of each cell.
