Investigation of phonons and magnons in [Ni80Fe20/Au/Co/Au]10 multilayers

Abstract
Abstract The dispersion relations of surface acoustic waves and spin waves propagating in magnetic [Ni80Fe20/Au/Co/Au]10 multilayers deposited on a silicon substrate have been investigated by high-resolution Brillouin spectroscopy. We measured the spectra of spin waves for two canonical geometries where the spin waves propagate with the wave vector oriented parallel and perpendicular to the direction of static magnetization in-plane magnetized Py layer. We investigated experimentally the crossing of phononic and magnonic dispersion relations and discussed the mechanism of magnetoelastic interaction in this system.
