Dynamic Magnetoelastic Boundary Conditions and the Pumping of Phonons
arXiv:2104.05992 · doi:10.1103/PhysRevB.104.014403
Abstract
We derive boundary conditions at the interfaces of magnetoelastic heterostructures under ferromagnetic resonance for arbitrary magnetization directions and interface shapes. We apply our formalism to magnetnonmagnet bilayers and magnetic grains embedded in a nonmagnetic thin film, revealing a nontrivial magnetization angle dependence of acoustic phonon pumping.
