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…
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…
