Generation and Imaging of Magnetoacoustic Waves over Millimeter Distances.
Physical review letters 124:13 (2020) 137202
Abstract:
Using hybrid piezoelectric-magnetic systems we have generated large amplitude magnetization waves mediated by magnetoelasticity with up to 25 degrees variation in the magnetization orientation. We present direct imaging and quantification of both standing and propagating acoustomagnetic waves with different wavelengths, over large distances up to several millimeters in a nickel thin film.Has Reducing Ship Emissions Brought Forward Global Warming?
