Paper Abstract

The ability to control magnetic domain patterns with high frequency strain waves could result in a novel, fast method for moving domain walls. We examine the motion of magnetic domain walls in Co/Pt multilayers when subject to a high frequency strain standing wave generated by a focused surface acoustic wave transducer. Our ability to map focused strain waves using optical methods allow us to make subsequent magnetic measurements without losing the location of strain nodes and antinodes. Our results indicate that domain walls move preferentially towards strain antinodes and away from the nodes.
