  The interaction between surface acoustic waves (SAWs) and spin waves (SWs) in
a piezoelectric-magnetic thin film heterostructure yields potential for the
realization of novel microwave devices and applications in magnonics. In the
present work, we characterize magnetoacoustic waves in three adjacent magnetic
micro-stripes made from CoFe+Ga, CoFe, and CoFe+Pt with a single pair of
tapered interdigital transducers (TIDTs). The magnetic micro-stripes were
deposited by focused electron beam-induced deposition (FEBID) and focused ion
beam-induced deposition (FIBID) direct-writing techniques. The transmission
characteristics of the TIDTs are leveraged to selectively address the
individual micro-stripes. Here, the external magnetic field is continuously
rotated out of the plane of the magnetic thin film and the forward volume SW
geometry is probed with the external magnetic field along the film normal. Our
experimental findings are well explained by an extended phenomenological model
based on a modified Landau-Lifshitz-Gilbert approach that considers SWs with
nonzero wave vectors. Magnetoelastic excitation of forward volume SWs is
possible because of the vertical shear strain $\varepsilon_{xz}$ of the
Rayleigh-type SAW.
