Abstract
Dynamic behaviors of transverse domain walls (TDWs) in rectangular shaped thin-film magnetic nanowires with different widths under applied magnetic fields less than the Walker field were studied by micromagnetic simulations. It was found that the velocity of stable TDWs in the viscous region increases from 147 to 419 ㎧ and their mass decreases from 6.24 × 10?²³ to 2.70 × 10?²³ ㎏ with increasing strength of the applied magnetic field ranging from 5 to 20 Oe for the nanowire with a dimension of 10 ㎚ in thickness and 5 ㎛ in length, and 50 ㎚ in width. With increasing the width of nanowires from 50 to 125 ㎚ at a specific field strength of 5 Oe, the TDW’s velocity also increases from 147 to 246 ㎧ and its mass decreases from 6.24 × 10?²³ to 5.91 × 10?²³ ㎏.
