In this paper, we experimentally characterize the domain-wall depinning mechanism at notches of ferromagnetic nanowires with perpendicular magnetic anisotropy. A time-resolved magneto-optical Kerr effect detection reveals that the depinning time is e

The energy barrier of a magnetic domain wall trapped at a defect is measured experimentally. When the domain wall is pushed by an electric current and/or a magnetic field, the depinning time from the barrier exhibits perfect exponential distribution,

We examine magnetic domain wall motion in metallic nanowires Pt-Co-Pt. Regardless of whether the motion is driven by either magnetic fields or current, all experimental data fall onto a single universal curve in the creep regime, implying that both t

The electric control of the motion of multiple domain walls (DWs) is demonstrated by using the Pt/Co/Pt nanotracks with perpendicular magnetic anisotropy. Because of the weak microstructural disorders with a small DW propagation field (approximately
