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…
Radio-frequency assisted switching in perpendicular magnetic tunnel junctions
Mark Hayward, Salvatore Perna, Massimiliano d'Aquino +5
Spin-transfer torque magnetic random-access memory (STT-MRAM) relies on nanoscale magnetic tunnel junctions (MTJs) as its fundamental building blocks. Next-generation STT-MRAM requ…
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…
Self-modulation instability in high power ferromagnetic resonance of BiYIG nanodisks
Igor Ngouagnia Yemeli, Salvatore Perna, Diane Gouéré +9
We study the high power ferromagnetic resonance (FMR) of perpendicularly magnetized BiYIG nanodisks where the uniaxial anisotropy almost compensates the shape anisotropy. We observ…
