Abstract The factors, which influence the internal stresses in glass coated amorphous microwires were discussed in this work in relation to the magnetization behaviour and domain wall propagation. The approach taking into account the technological parameters of manufacturing by Ulitovsky-Taylor method is presented. The magnetization process and domain wall dynamics in Fe77.5Si7.5B15 microwires produced under different conditions but with identical geometric parameters were investigated experimentally and analysed on the basis of internal stress formation in different microwire states: as prepared, after glass removal and after annealing. It is demonstrated that the residual stresses in wires of the same composition are not defined exclusively by their dimensions but depend on the technological regime. The stress modification due to relaxing treatments also proceeds differently in wires produced under different conditions. These conclusions are evidenced by comparing the domain wall mobilities which strongly depend on the internal stress.

通过应力调整固定尺寸的 Fe-Si-B 非晶微丝来控制静磁和动态特性

摘要 本文讨论了影响玻璃涂层非晶微线内应力的因素，这些因素与磁化行为和畴壁传播有关。介绍了考虑到 Ulitovsky-Taylor 方法制造工艺参数的方法。在不同条件下生产但具有相同几何参数的 Fe77.5Si7.5B15 微线的磁化过程和畴壁动力学进行了实验研究，并基于不同微线状态下的内应力形成进行了分析：制备、玻璃去除后和退火后。结果表明，相同成分的线材中的残余应力不仅仅由它们的尺寸定义，还取决于技术方案。在不同条件下生产的线材中，由于松弛处理引起的应力改变也不同。通过比较强烈依赖于内应力的畴壁迁移率来证明这些结论。
