通过巨磁阻(GMR)测量研究了具有晶体各向异性和形状各向异性的单晶铁线中磁畴壁(DW)的磁化反转特征。在 77 K 的 110 Oe 场中,DW 传播速度达到约 1 km/s。在纵轴平行于⟨110⟩ 方向的铁丝中,发现了传播速度与切换场的广泛分布。包括晶体和形状各向异性在内的磁各向异性能量在 DW 的成核和传播中起着重要作用。
The characterization of magnetization reversal in a magnetic domain wall (DW) in a single crystalline Fe wire with crystalline anisotropy and shape anisotropy has been investigated by the giant magnetoresistance (GMR) measurement. The DW propagation velocity reached about 1 km/s in 110 Oe field at 77 K. The broad distribution of the propagation velocity versus the switching field in the Fe wire with longitudinal axis parallel to the ⟨110⟩ direction was found. The magnetic anisotropy energy including the crystalline and shape anisotropies play an important role in the nucleation and propagation of DW.
