Abstract

Domain reversal of Co/Pd multilayers with varying the Pd-sublayer thickness has been quantitatively investigated. The magnetization viscosity measurement and the magnetic domain observation in real time showed that the reversal behavior was gradually changed from nucleation dominant to wall-motion dominant with increasing Pd-sublayer thickness. Both the wall-motion speed and the nucleation rate of the samples were determined by the quantitative analysis based on time-dependent domain patterns. The change in reversal behavior was found to be ascribed to the change in the magnetic properties with increasing Pd-sublayer thickness
