Abstract

The present study utilized Y₃Fe₅O₁₂ (YIG) ferrites as a coating on Fe-Si-B-Cu-Zr nanocrystalline magnetic powder to fabricate soft magnetic composites (SMCs). The influence of YIG content and annealing temperature on the magnetic properties of Fe-Si-B-Cu-Zr/YIG SMCs was investigated. It was revealed that an appropriate amount of YIG in the composite could enhance the permeability and its resistance to DC bias, while reducing eddy current loss. The results demonstrated that the Fe-Si-B-Cu-Zr/YIG SMCs coated with 1.0 wt% YIG exhibited good comprehensive magnetic properties, with a permeability of 33.8, 86.1 % retention under a DC bias of 100 Oe, and a 53.1 % reduction in eddy current loss to 13.86 mW/cm³ at 500 kHz and 10 mT. Besides, the optimal annealing temperature for achieving decrease core loss and maximum permeability was determined to be 500℃ for the Fe-Si-B-Cu-Zr/YIG SMCs. This study demonstrates a promising coating material to enhance the high-frequency magnetic properties of nanocrystalline soft magnetic composite.

具有YIG铁氧体绝缘层的Fe-Si-B-Cu-Zr纳米晶软磁复合材料的高频磁性能

本研究利用Y3Fe5O12 （YIG）铁氧体包覆在Fe-Si-B-Cu-Zr纳米晶磁粉上制备软磁复合材料。研究了YIG含量和退火温度对Fe-Si-B-Cu-Zr/YIG SMCs磁性能的影响。结果表明，在复合材料中加入适量的YIG可以提高材料的磁导率和抗直流偏置，同时减少涡流损耗。结果表明Fe-Si-B-Cu-Zr /钇铁石榴石smc涂上1.0 wt %钇铁石榴石表现出良好的综合磁性,磁导率为33.8,86.1%保留直流偏压下的100 Oe和涡流损耗减少53.1%在500 kHz 13.86 mW /立方厘米,10吨。此外,实现降低核心的最佳退火温度和最大渗透率损失决心Fe-Si-B-Cu-Zr /钇铁石榴石smc是500℃。本研究为提高纳米晶软磁复合材料的高频磁性提供了一种很有前途的涂层材料。

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.
