Spin-wave softening across the uniform-to-stripe domain transition in iron garnet film
Titiksha Srivastava, Victor Leroy, Nessrine Benaziz +6
Spin-wave spectra across transitions between uniform and textured phases can offer deep insight into both symmetry-breaking physics and self-assembled magnonic bands. However, expe…
Field-driven triggering of self-induced Floquet magnons in a magnetic vortex
R. Lopes Seeger, G. Philippe, A. Jenkins +5
We report the experimental control of Floquet magnons in a magnetic vortex. Using microwave spectroscopy of vortex state magnetic tunnel junctions (MTJs), we find that self-induced…
Predicting the future with magnons
Zeling Xiong, Christopher Heins, Thibaut Devolder +5
Forecasting complex, chaotic signals is a central challenge across science and technology, with implications ranging from secure communications to climate modeling. Here we demonst…
Electrical magnon spectroscopy with foundry-fabricated nanoscale magnetic tunnel junctions
Christopher Heins, Zeling Xiong, Attila Kákay +10
Magnonics uses spin waves and their quanta, magnons, to carry and process information and offers new opportunities for computing and signal processing. Its integration with convent…
Self-induced Floquet states via three-wave processes in synthetic antiferromagnets
Thibaut Devolder, Joo-Von Kim
We present a mechanism for self-induced Floquet states involving acoustic and optical modes in synthetic antiferromagnets. By driving optical modes off-resonantly with radiofrequen…
Method of analysis of the spectra obtained by microfocused Brillouin light scattering
Nessrine Benaziz, Thibaut Devolder, Jean-Paul Adam
Brillouin Light Scattering is a powerful technique to measure the microwave excitations present in a magnetic system. In microfocused mode, the light is focused on the sample using…
Spin waves involved in three-magnon splitting in synthetic antiferromagnets
Asma Mouhoub, Nathalie Bardou, Jean-Paul Adam +2
An important nonlinear effect in magnonics is the 3-magnon splitting where a high frequency magnon splits into two magnons of lower frequencies. Here, we study the 3-magnon splitti…
Role of non-reciprocity in spin-wave channeling
Jean-Paul Adam, Nathalie Bardou, Aurélie Solignac +2
The extent to which non-reciprocal waves can be guided in arbitrary directions is an interesting question. We address one aspect of this problem by studying the propagation of acou…
Self-induced Floquet magnons in magnetic vortices
Christopher Heins, Lukas Körber, Joo-Von Kim +6
Driving condensed matter systems with periodic electromagnetic fields can result in exotic states not found in equilibrium. Termed Floquet engineering, such periodic driving applie…
Exchange stiffness in ultrathin perpendicularly-magnetized CoFeB layers determined using spin wave spectroscopy
T. Devolder, J. -V. Kim, L. Nistor +3
We measure the frequencies of spin waves in nm-thick perpendicularly magnetized FeCoB systems, and model the frequencies to deduce the exchange stiffness of this material in the ul…
Modulating spin transfer torque switching dynamics with two orthogonal spin-polarizers by varying the cell aspect ratio
B. Lacoste, M. Marins de Castro, T. Devolder +9
We study in-plane magnetic tunnel junctions with additional perpendicular polarizer for subnanosecond-current-induced switching memories. The spin-transfer-torque switching dynamic…
