Abstract

Nanocrystalline and amorphous alloys are extensively utilized as core materials in devices such as motors and transformers. Their magnetic properties can be altered by stress, significantly impacting the operational efficiency and reliability of electrical equipment. In this study, a wide-frequency-range magnetic property testing system capable of applying out-of-plane stress is designed. The design of the stress application components and the uniformity of stress distribution in the samples are thoroughly analyzed through simulations. This system is used to measure the changes in the magnetic properties of nanocrystalline and amorphous alloy sheets under out-of-plane stress over a wide frequency range. The test results indicate that the out-of-plane stress applied to nanocrystalline alloys leads to an increase in the core loss. The core loss in amorphous alloys initially decreases and subsequently increases at frequencies exceeding the kilohertz range.

宽频面外应力作用下非晶和纳米晶合金的磁性能测试

纳米晶和非晶合金被广泛用作电机和变压器等器件的铁芯材料。它们的磁性可以被应力改变，显著影响电气设备的运行效率和可靠性。本文设计了一种能承受面外应力的宽频域磁性能测试系统。通过仿真对施加应力元件的设计和试样应力分布的均匀性进行了深入分析。该系统用于在宽频率范围内测量面外应力作用下纳米晶和非晶合金片的磁性能变化。试验结果表明，施加在纳米晶合金上的面外应力导致铁芯损耗增大。在超过千赫兹的频率范围内，非晶合金的铁心损耗先减小后增大。

期刊介绍： The Journal of Magnetism and Magnetic Materials provides an important forum for the disclosure and discussion of original contributions covering the whole spectrum of topics, from basic magnetism to the technology and applications of magnetic materials. The journal encourages greater interaction between the basic and applied sub-disciplines of magnetism with comprehensive review articles, in addition to full-length contributions. In addition, other categories of contributions are welcome, including Critical Focused issues, Current Perspectives and Outreach to the General Public. Main Categories: Full-length articles: Technically original research documents that report results of value to the communities that comprise the journal audience. The link between chemical, structural and microstructural properties on the one hand and magnetic properties on the other hand are encouraged. In addition to general topics covering all areas of magnetism and magnetic materials, the full-length articles also include three sub-sections, focusing on Nanomagnetism, Spintronics and Applications. The sub-section on Nanomagnetism contains articles on magnetic nanoparticles, nanowires, thin films, 2D materials and other nanoscale magnetic materials and their applications. The sub-section on Spintronics contains articles on magnetoresistance, magnetoimpedance, magneto-optical phenomena, Micro-Electro-Mechanical Systems (MEMS), and other topics related to spin current control and magneto-transport phenomena. The sub-section on Applications display papers that focus on applications of magnetic materials. The applications need to show a connection to magnetism. Review articles: Review articles organize, clarify, and summarize existing major works in the areas covered by the Journal and provide comprehensive citations to the full spectrum of relevant literature.
