Extrinsic pinning of magnetic domain walls in CoFeB-MgO nanowires with perpendicular anisotropy
In this work, we have studied the mechanism of domain wall motion in 0.2-1.5 μm wide nanowires based on Ta/CoFeB/MgO films with perpendicular magnetic anisotropy. We show that domain wall propagation can be completely stopped due to the presence of strong pinning sites along the nanowires. From the...
