Abstract

The presence of anisotropy in the properties of materials presents challenges for their characterization. This is particularly relevant for magnetic materials, which are often sensitive to external fields. As such, the characterization of magnetic materials is a complex task. In this study, we propose extending the frequency range of the classic single-turn inductor method for disc-shaped samples with holes into the GHz range, utilizing numerical methods provided by Ansoft HFSS software. The measurement of the components of the magnetic permeability tensor depends on the direction of the applied magnetic field. To change the magnetic field direction, we developed a microstrip measurement setup for the same disc-shaped sample. Due to the complexity of the underlying mathematical model, we employed numerical methods to calculate the magnetic permeability.

采用扩展单匝电感和微带方法的高频磁导率表征

材料性能的各向异性对表征提出了挑战。这对于经常对外部磁场敏感的磁性材料尤其重要。因此，磁性材料的表征是一项复杂的任务。在这项研究中，我们提出利用Ansoft HFSS软件提供的数值方法，将经典的单匝电感法用于带孔圆盘状样品的频率范围扩展到GHz范围。磁导率张量分量的测量取决于外加磁场的方向。为了改变磁场方向，我们开发了一种微带测量装置，用于相同的圆盘状样品。由于底层数学模型的复杂性，我们采用数值方法计算磁导率。

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.
