Hyperchaos in a Magnetic Nanodisk Driven by Ferromagnetic Resonance
A Kolli, Hugo Merbouche, Salvatore Perna +3
The paper investigates chaotic and hyperchaotic dynamics in an out-of-plane magnetized nanodisk driven by ferromagnetic resonance, using micromagnetic simulations and time‑series a…
Nonlinear interaction theory for parametrically-excited spin-wave modes in confined micromagnetic systems
Massimiliano d'Aquino, Salvatore Perna, Hugo Merbouche +1
We present a general theoretical approach for the quantitative description of parametric excitation of spin-wave modes in confined micromagnetic systems. This type of problem belon…
Field Theory of Linear Spin-Waves in Finite Textured Ferromagnets
Thierry Valet, Kei Yamamoto, Benjamin Pigeau +2
In the context of an ever-expanding experimental and theoretical interest in the magnetization dynamics of mesoscopic magnetic structures, both in the classical and quantum regimes…
The Orbital Angular Momentum of Azimuthal Spin-Waves
Thierry Valet, Kei Yamamoto, Benjamin Pigeau +2
In the context of a growing interdisciplinary interest in the angular momentum of wave fields, the spin-wave case has yet to be fully explored, with the extensively studied notion…
Nonlinear mode interactions under parametric excitation in a YIG microdisk
Gabriel Soares, Rafael Lopes Seeger, Amel Kolli +13
A pair of quantized spin-wave modes is driven by two-tone parallel pumping in a YIG microdisk. The nonlinear dynamics is experimentally investigated by probing the resulting steady…
Experimental observation of vortex gyrotropic mode excited by surface acoustic waves
R. Lopes Seeger, F. Millo, G. Soares +4
The traditional method for exciting spin-wave dynamics in magnetic materials involves microwave magnetic fields generated by current injection into inductive antennas. However, the…
