Unidirectional Pumping of Phonons by Magnetization Dynamics
arXiv:2003.02519 · doi:10.1103/PhysRevLett.125.077203
Abstract
We propose a method to control surface phonon transport by weak magnetic fields based on the pumping of surface acoustic waves (SAWs) by magnetostriction. We predict that the magnetization dynamics of a nanowire on top of a dielectric films injects SAWs with opposite angular momenta into opposite directions. Two parallel nanowires form a phononic cavity that at magnetic resonances pump a unidirectional SAW current into half of the substrate.
