Abstract
Current-induced domain wall motion on a magnetic strip has been studied for its potential application to magnetic logic and memory devices. In this study, we carried out a series of calculations to investigate the changes of the domain wall velocity and width as a function of the notch shape using the Landau-Lifschitz-Gilbert solver. The domain wall had a uniform velocity when the notches were shallow and wide, while the width of the domain wall became narrow when the notches were deep and narrow. To produce a domain wall structure with both a uniform velocity and a narrow width, an asymmetric notch shape was devised.
