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…
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…
