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…
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 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…
Unidirectional spin waves measured using propagating spin wave spectroscopy
G. Y. Thiancourt, S. M. Ngom, N. Bardou +1
The dispersion relation of spin waves can vary monotonically about the center of the Brillouin zone, allowing zero-momentum wavepackets to flow unidirectionally, which is of intere…
Spectroscopy of the spin waves of a synthetic antiferromagnet grown on a piezoelectric substrate
G. Y. Thiancourt, S. M. Ngom, N. Bardou +1
Efficient coupling between magnons and phonons requires material platforms that contain magnetic multilayers with versatile high-frequency properties grown on piezoelectric substra…
