摘要

高灵敏度磁传感器是生物医学和无损检测等领域的基础元件。磁通量浓缩技术通过放大待测磁场来提高磁传感器的灵敏度，是提高磁传感器磁场分辨率的最有效方法。超导体和高渗透软磁材料表现出完全不同的磁效应。前者具有完全的二磁性，而后者则具有极高的磁导率。这两种材料都可用于制造磁通量集中器。本文通过理论模拟和实验比较了超导和软磁磁通量集中技术，研究了不同结构参数对超导和软磁集中器磁场放大性能的影响。这项研究对于磁聚焦技术的发展及其在弱磁探测和其他领域的应用具有重要意义。

Magnetic Flux Concentration Technology Based on Soft Magnets and Superconductors

High-sensitivity magnetic sensors are fundamental components in fields such as biomedicine and non-destructive testing. Flux concentration technology enhances the sensitivity of magnetic sensors by amplifying the magnetic field to be measured, making it the most effective method to improve the magnetic field resolution of magnetic sensors. Superconductors and high-permeability soft magnetic materials exhibit completely different magnetic effects. The former possesses complete diamagnetism, while the latter has extremely high magnetic permeability. Both types of materials can be used to fabricate flux concentrators. This paper compares superconducting and soft magnetic flux concentration technologies through theoretical simulations and experiments, investigating the impact of different structural parameters on the magnetic field amplification performance of superconducting and soft magnetic concentrators. This research is significant for the development of magnetic focusing technology and its applications in weak magnetic detection and other fields.

期刊介绍： Crystals (ISSN 2073-4352) is an open access journal that covers all aspects of crystalline material research. Crystals can act as a reference, and as a publication resource, to the community. It publishes reviews, regular research articles, and short communications. Our aim is to encourage scientists to publish their experimental and theoretical results in as much detail as possible. Therefore, there is no restriction on article length. Full experimental details must be provided to enable the results to be reproduced. Crystals provides a forum for the advancement of our understanding of the nucleation, growth, processing, and characterization of crystalline materials. Their mechanical, chemical, electronic, magnetic, and optical properties, and their diverse applications, are all considered to be of importance.
