Hyperchaos in a Magnetic Nanodisk Driven by Ferromagnetic Resonance
A Kolli, Hugo Merbouche, Salvatore Perna +3
We investigate the chaotic dynamics driven in the nonlinear regime of ferromagnetic resonance of an out-of-plane magnetized nanodisk in detail. By combining extensive micromagnetic…

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…
