Field dependence of the activation volumes in Co/Pd multilayered films

Abstract

The field dependence of the activation volumes of nucleation and wall-motion processes in magnetization reversal of Co/Pd multilayers is presented, as observed using a magneto-optical Kerr-effect microscope capable of real-time domain imaging in a wide time range of 10−5−103 s. The analytic forms of the activation volumes are derived from a theoretical… (More)
