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…
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…
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…
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 detection of magnons with nanoscale magnetic tunnel junctions
Christopher Heins, Zeling Xiong, Attila Kákay +10
Present information and communication technologies are largely based on electronic devices, which suffer from heat generation and high power consumption. Alternatives like spintron…
