Driving skyrmions in flow regime in synthetic ferrimagnets
Sougata Mallick, Yanis Sassi, Nicholas Figueiredo Prestes +11
Despite significant advances in the last decade regarding the room temperature stabilization of skyrmions or their current induced dynamics, the impact of local material inhomogene…
True amplification of spin waves in magnonic nano-waveguides
Hugo Merbouche, Boris Divinskiy, Diane Gouéré +7
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…
X-ray holography of skyrmionic cocoons in aperiodic magnetic multilayers
M. Grelier, R. Battistelli, H. Popescu +9
The development and characterization of three-dimensional (3D) topological magnetic textures has become an important topic in modern magnetism both for fundamental and technologica…
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…
Complete identification of spin-wave eigenmodes excited by parametric pumping in YIG microdisks
Titiksha Srivastava, Hugo Merbouche, Igor Ngouagnia Yemeli +15
We present the parametric excitation of spin-wave modes in YIG micro-disks via parallel pumping. Their spectroscopy is performed using magnetic resonance force microscopy (MRFM), w…
Compensation of anisotropy in spin-Hall devices for neuromorphic applications
Pankaj Sethi, Dédalo Sanz-Hernández, Florian Godel +6
Spintronic nano-oscillators with reduced non-linearity could offer key benefits for realizing neuromorphic applications such as spike-based neurons and frequency multiplexing in ne…
