We have investigated the effects of high frequency strain on domain wall (DW) textures in ferromagnetic thin films with perpendicular anisotropy. Matched pairs of interdigital transducers are lithographically patterned on 128 Y cut LiNbO3. Excitation at the resonance frequency drives surface acoustic waves (SAW). We describe the response of domain walls (DW) and magnetic bubbles. SAW lower the pinning energy barriers of DWs, showing a monotonic decrease in the characteristic depinning time with SAW amplitude. Application of SAW in a different sample rapidly increases the density of bubbles. We measure SAW driven dynamics of bubble domains.
