Domain walls in magnetic thin films are being explored for memory applications and the speed at which they move has acquired increasing importance. Magnetic fields currents have been shown to drive domain with speeds exceeding 500 m/s. We investigate another approach increase wall velocities, using high frequency surface acoustic waves create standing strain a 3 micron wide strip of film perpen...

Domain wall dynamics in thin magnetic films with perpendicular and in-plane anisotropy is studied using a novel magneto-optical Kerr effect susceptometery method. The method allows for measurements of domain wall motion under ac field excitation and the analysis of dynamic modes as a function of driving frequency and magnetic field amplitude. Domain wall dynamics in the perpendicular anisotropy...
