Query: The studies on phonons and magnons in (Ni80Fe20/Au/Co/Au) multilayers of
  different number of repetitions   In Ni80Fe20/Au/Co/Au deposited on silicon substrate the interaction between
spin waves and surface acoustic waves is observed by Brillion light scattering
spectroscopy. We show that by changing the number of receptions in the
multilayer we can tune the dispersion of surface acoustic waves (SAWs) not
affecting significantly fundamentals spin wave (SW) mode. As a result, we can
control (activate or deactivate) the magnetoelastic interaction between
fundamental SW mode and SAWs by the thickness of the magnetostrictive
multilayer.
