Micromagnetic study on the threshold current density for continuous domain wall motion
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.
