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 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…
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…
Stimulated magnon scattering by non-degenerate parametric excitation
Joo-Von Kim, Hugo Merbouche
Parametric spin wave excitation allows studying a variety of nonlinear phenomena, such as magnon scattering. In patterned micro- and nanostructures the magnon spectra is discrete a…

We study experimentally the processes of parametric excitation in microscopic magnetically saturated disks of nanometer-thick Yttrium Iron Garnet. We show that, depending on the re…
True amplification of spin waves in magnonic nano-waveguides

Magnonic nano-devices exploit magnons -- quanta of spin waves -- to transmit and process information within a single integrated platform that has the potential to outperform tradit…
Temperature-independent ferromagnetic resonance shift in Bi-doped YIG garnets through magnetic anisotropy tuning
Diane Gouéré, Hugo Merbouche, Aya El Kanj +8
Thin garnet films are becoming central for magnon-spintronics and spin-orbitronics devices as they show versatile magnetic properties together with low magnetic losses. These field…

This review provides a comprehensive study of the nonlinear transport properties of magnons, which are electrically emitted or absorbed inside extended YIG films by spin transfer e…
Evidence for spin current driven Bose-Einstein condensation of magnons
B. Divinskiy, H. Merbouche, V. E. Demidov +9
The quanta of magnetic excitations - magnons - are known for their unique ability to undergo Bose-Einstein condensation at room temperature. This fascinating phenomenon reveals its…
