Brillouin light scattering was used to study surface acoustic wave propagation in platinum (111) and ruthenium (0001) single crystals, both clean and loaded with a few-nanometre-thick epitaxial magnetite (111) film. The results revealed the influence of the film loading on the velocity of surface acoustic wave propagation in the studied samples. The surface acoustic modes were additionally analysed by finite element method simulations.
