This paper investigates the possible transitions between transverse and vortex type domain walls in magnetic domain wall trap memory elements, induced by a rotating magnetic field. A phase relation is shown to exist relating the final domain wall configuration to the field strength and field rotation frequency. Thus, it is possible to controllably switch from a transverse domain wall to either a clockwise or counterclockwise one.
