摘要

如今，新的雄心勃勃的研究致力于磁性材料的传感技术突出了理解控制磁化过程的方法的重要性。在各种快速磁化过程的软磁材料中，价格低廉、具有超强磁性的软铁基铁磁玻璃包覆微线脱颖而出。本文实验研究了非晶Fe77.5Si7.5B15和Fe77Si10B10C3铁磁玻璃微丝的畴壁运动。利用改进的Sixtus-Tonks方法，计算了非均匀性分布和杂散场对DW运动参数（速度、局部成核场）的影响。首先确定了三种DW运动机构。建立了考虑机械缺陷影响的DW速度整定模型。本文的研究有助于减少基于磁畴壁运动机理的敏感器件的响应时间。

Non-uniform domain wall propagation in Fe-based magnetic microwires

Nowadays the novel ambitious studies dedicated to magnetic materials for sensing technologies highlights the importance of understanding the ways of control the magnetization process. Among variety of soft magnetic materials with fast magnetization process the cheap in production and ultra magnetically soft Fe-based ferromagnetic glass-coated microwires stands out.

In this paper, we experimentally studied the domain wall (DW) motion in amorphous Fe_77.5Si_7.5B₁₅ and Fe₇₇Si₁₀B₁₀C₃ ferromagnetic glass-coated microwires. Using the modified Sixtus-Tonks method the influence of the inhomogeneities distribution and the effect of stray fields on the parameters of DW motion (velocity, local nucleation fields) have been evaluated. Three types of DW motion mechanism were firstly identified. And the model of DW velocity tuning with the mechanical defects influence is presented. This study could lead to decrease the response time of sensitive devices which are based on magnetic domain wall motion mechanism.

期刊介绍： This journal is a platform for publishing innovative research and overviews for advancing our understanding of the structure, property, and functionality of complex metallic alloys, including intermetallics, metallic glasses, and high entropy alloys. The journal reports the science and engineering of metallic materials in the following aspects: Theories and experiments which address the relationship between property and structure in all length scales. Physical modeling and numerical simulations which provide a comprehensive understanding of experimental observations. Stimulated methodologies to characterize the structure and chemistry of materials that correlate the properties. Technological applications resulting from the understanding of property-structure relationship in materials. Novel and cutting-edge results warranting rapid communication. The journal also publishes special issues on selected topics and overviews by invitation only.
