Abstract
We report micromagnetic modeling results of current induced domain wall (DW) motion in magnetic devices with perpendicular magnetic anisotropy by solving the LandauLifschitzGilbert equation including adiabatic and non-adiabatic terms. A nanostripe model system with dimensions of 500 nm (L)×25 nm (W)×5 nm (H) was selected for calculating the DW motion and its width, as a function of various parameters such as non-adiabatic contribution, anisotropy constant (Ku), saturation magnetization (Ms), and temperature (T). The DW velocity was found to increase when the values of Ku and T were increased and the Ms value decreased. In addition, a reduction of the domain wall width could be achieved by increasing Ku and lowering Ms values regardless of the non-adiabatic constant value.
