Magnon-polarons are coherently mixed quasiparticles that originate from thestrong magnetoelastic coupling of lattice vibrations and spin waves inmagnetic-ordered materials. Recently, magnon-polarons have attracted a lot ofattention since they provide a powerful tool to manipulate magnons, which isessential for magnon-based spintronic devices. In this work, we report theexperimental observation of facet-dependent magnon-polarons in epitaxialferrimagnetic Fe3O4 thin films via spin Seebeck effect measurement. Thecritical magnetic fields for the magnon-polarons in the (110)- and(100)-oriented Fe3O4 films are 1.5 T and 1.8 T, respectively, which arises fromthe different phonon velocities along the [110] and [100] directions. As thetemperature decreases, the magnon-polarons-enhanced spin Seebeck voltagedecreases in both (110)- and (100)-oriented Fe3O4 films, which could beattributed to the enhanced magnon-polarons scattering at elevated temperatures.This work demonstrates the crystal structure engineering in epitaxial magneticfilms as a promising route to manipulate the magnon-polarons for future magnonspintronic applications.
