摘要/Abstract

摘要： 设计软磁复合材料(SMCs)的绝缘层要兼顾软磁性能和电阻率。本研究以Fe/Ni_0.5Zn_0.5Fe₂O₄复合体系为例, 研究界面MnO₂氧化剂对样品软磁性能和电阻率的影响, 揭示提高软磁性能和电阻率的SMCs界面放电等离子烧结(SPS)氧化还原机制。采用球磨法制备添加0、0.1wt%、0.3wt%、0.5wt%和1.0wt% MnO₂的核壳结构Fe@Ni_0.5Zn_0.5Fe₂O₄(MnO₂)复合粉末, 随后SPS烧结制备Fe/Ni_0.5Zn_0.5Fe₂O₄(MnO₂)块体SMCs样品, 通过扫描电镜(SEM)、X射线衍射(XRD)表征该样品的结构特征, 用精密电阻测试仪和振动样品磁强计测试该样品的电阻率和磁性能。研究发现, 添加0.5wt% MnO₂的Fe/Ni_0.5Zn_0.5Fe₂O₄(MnO₂)块体SMCs样品比未添加样品电阻率提高33.7%、饱和磁化强度提高6.9%。研究结果表明, SPS烧结增强SMCs界面快速氧化还原反应, MnO₂氧化剂的添加使界面铁氧体离子浓度变化, 降低了B位电子跃迁频率, 提高有效波尔磁子数及B-B磁超交换作用, 表现出同时提高SMCs的软磁性能和电阻率的多重效应。

Abstract: The design trend of the insulating layer of soft magnetic composite materials (SMCs) is to consider both their soft magnetic properties and resistivity. In this study, using Fe/Ni_0.5Zn_0.5Fe₂O₄ composite system as an example, the influence of MnO₂ oxidant on the soft magnetic properties and resistivity of the samples is studied, and the redox mechanism resulting from spark plasma sintering (SPS) at SMCs interface which improves the soft magnetic properties and resistivity is revealed. The Fe@Ni_0.5Zn_0.5Fe₂O₄(MnO₂) core-shell composite powders with different amount of MnO₂ (0, 0.1wt%, 0.3wt%, 0.5wt%, 1.0wt%) are prepared by ball milling, the Fe/Ni_0.5Zn_0.5Fe₂O₄(MnO₂) bulk SMCs are prepared by SPS. Their structures are characterized by SEM and XRD, and their electromagnetic properties are tested by precise resistance tester and vibrating sample magnetometer. It is found that the resistivity of Fe/Ni_0.5Zn_0.5Fe₂O₄(MnO₂) bulk SMCs with 0.5wt% MnO₂ is 33.7% higher than that without MnO₂, the saturation magnetic induction strength is 6.9% higher. The results show that the SPS sintering enhances the rapid REDOX reaction at the SMCs interface, and the addition of MnO₂ oxidants changes the ions concentration of ferrite at the SMCs interface, shows multiple effects of simultaneously improving the soft magnetic properties and resistivity of SMCs, because it reduces the B-bit electron transition frequency, increases the effective Bohr magneton number, and improves the B-B magnetic superexchange.
