  • Abstract
    Theoretical study by Tatara and Kohno predicted the threshold current density (Jc) above which spin current enables the continuous domain wall motion in the adiabatic limit [1]. We investigated on this point by micromagnetic simulation. It was found out that Jc is proportional to the product of the hard-axis anisotropy and the domain wall width as predicted in [1]. However, Jc was much lower than the predicted value.
