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…
Time-resolved observation of magnon splitting into vortex gyration and Floquet spin waves
T. Devolder, R. Lopes Seeger, C. Heins +9
Forced excitations at frequencies in the range of the first order azimuthal spin waves of a magnetic disk in the vortex state are known to scatter into the vortex gyration mode, th…
Symmetry of the dissipation of surface acoustic waves by ferromagnetic resonance
Florian Millo, Rafael Lopes Seeger, Claude Chappert +2
We study the symmetry of the coupling between surface acoustic waves and ferromagnetic resonance in a thin magnetic film of CoFeB deposited on top of a piezoelectric Z-cut LiNbO3 s…
Experimental observation of vortex gyrotropic mode excited by surface acoustic waves
R. Lopes Seeger, F. Millo, G. Soares +4
The traditional method for exciting spin-wave dynamics in magnetic materials involves microwave magnetic fields generated by current injection into inductive antennas. However, the…
Symmetry of the coupling between surface acoustic waves and spin waves in synthetic antiferromagnets
R. Lopes Seeger, L. La Spina, V. Laude +9
Synthetic antiferromagnets host spin waves that are highly tunable. It is of practical interest to analyze the symmetry of their coupling to surface acoustic waves with the design…
