Abstract

We studied the magnetic properties and Giant Magnetoimpedance (GMI) effect in amorphous Co-rich microwires with similar chemical compositions and different diameters with magnetic (Co, Permalloy) and non-magnetic (Cu) layers deposited by magnetic sputtering onto glass-coating. Studies of magnetic properties and GMI effect of as-prepared microwires and the same microwires with deposited magnetic and non-magnetic layers reveal substantial impact of such layers on GMI effect and hysteresis loops. Both as-prepared samples present soft magnetic properties and high GMI effect. The contribution of magnetic layers is observed in hysteresis loop at higher magnetic field, with hysteresis loops similar to those observed in microwires with mixed amorphous-crystalline structure. Meanwhile, both magnetic and non-magnetic layers affect low field hysteresis loops of both samples. Additionally, the GMI ratio, ΔZ/Z, and magnetic field dependences of GMI ratio are substantially affected by the presence of magnetic and non-magnetic layers deposited onto glass-coating. We discussed the observed experimental dependences considering both change of the internal stresses originated by the sputtered layer as well as the magnetostatic interaction between the amorphous ferromagnetic nucleus and deposited magnetic layers.

多层微导线中磁性能的调谐与巨磁阻抗效应

采用磁溅射法制备磁性（Co, Permalloy）层和非磁性（Cu）层的非晶富Co微线，研究了化学成分相似、直径不同的非晶富Co微线的磁性能和巨磁阻抗效应。通过对制备的微丝以及沉积磁性层和非磁性层的微丝的磁性能和GMI效应的研究，揭示了这些层对GMI效应和磁滞回线的实质性影响。两种制备的样品均具有软磁性能和高GMI效应。在高磁场条件下，磁层对磁滞回线的贡献与混合非晶结构微线的磁滞回线相似。同时，磁性层和非磁性层都会影响两种样品的低场磁滞回线。此外，GMI比、ΔZ/Z和GMI比对磁场的依赖很大程度上受到沉积在玻璃涂层上的磁性和非磁性层的影响。我们讨论了观察到的实验依赖关系，考虑了溅射层引起的内应力变化以及非晶铁磁核与沉积磁层之间的静磁相互作用。

期刊介绍： In 1985, the Journal of Science was founded as a platform for publishing national and international research papers across various disciplines, including natural sciences, technology, social sciences, and humanities. Over the years, the journal has experienced remarkable growth in terms of quality, size, and scope. Today, it encompasses a diverse range of publications dedicated to academic research. Considering the rapid expansion of materials science, we are pleased to introduce the Journal of Science: Advanced Materials and Devices. This new addition to our journal series offers researchers an exciting opportunity to publish their work on all aspects of materials science and technology within the esteemed Journal of Science. With this development, we aim to revolutionize the way research in materials science is expressed and organized, further strengthening our commitment to promoting outstanding research across various scientific and technological fields.
