Abstract

A theoretical model is proposed for structures of collective micromagnetic spin in magnetoresistive FeNiCo nanostrips with perpendicular anisotropy. Atypical dependences of the magnetoresistance on the magnitude of the external field obtained experimentally indicate there is a complex domain structure in each sample. The curves of the AMR effect, calculated in accordance with this model, are in quantitative agreement with the experimental results for the above samples, while calculations using the specialized OOMMF package show only qualitative similarities.

具有垂直各向异性的磁条中的AMR效应特征

摘要

提出了磁各向异性FeNiCo纳米带中具有垂直各向异性的集体微磁自旋结构的理论模型。通过实验获得的磁阻对外部磁场大小的非典型依赖性表明，每个样品中都有复杂的畴结构。根据该模型计算出的AMR效应曲线与上述样品的实验结果在数量上吻合，而使用专用OOMMF软件包进行的计算仅显示出定性相似性。
