Valley-selective phonon-magnon scattering in magnetoelastic superlattices
Phonons and magnons are engineered by periodic potential landscapes in phononic and
magnonic crystals, and their combined studies may enable valley phonon transport tunable …

Nonreciprocal magnetoacoustic waves with out-of-plane phononic angular momenta
Surface acoustic wave (SAW) can carry phononic angular momentum, showing great
potential as an energy-efficient way to control magnetism. Still, out-of-plane phononic …
