Fe基合金薄带GMI效应与驱动线圈磁芯填充系数的研究
Study of the GMI Effect on Thin Strips of Fe-Based Alloys and the Core Filling Factor of Drive Coils
摘要: 本文研究了以Fe基合金薄带(Fe85.67Si7.4B1.7Cu1.3Nb3.9C0.03)作为磁芯的纵向巨磁阻抗效应与其驱动线圈磁芯填充系数之间的数量关系。研究结果表示，Fe基磁芯驱动线圈的磁芯填充系数对纵向巨磁阻抗效应(LDGMI)有着不可忽视的作用。当磁芯填充系数增大时，磁芯驱动线圈的纵向巨磁阻抗效应会变得更加明显。当驱动线圈的截面积增大时，磁芯驱动线圈的最大阻抗比(ΔZ/Z)max会呈现幂函数性减小；当磁芯填充系数与磁芯驱动线圈的最大阻抗比(ΔZ/Z)max之间存在幂函数关系。
Abstract: In this paper, the quantitative relationship between the longitudinal giant magnetic impedance effect (LDGMI) of a thin strip of Fe-based alloy (Fe85.67Si7.4B1.7Cu1.3Nb3.9C0.03) as a magnetic core and the core filling factor of its drive coil is investigated. The results of the study indicated that the core filling factor of the drive coil of Fe-based cores has a non-negligible role in the longitudinal giant magnetic impedance effect (LDGMI). When the core filling factor increases, the longitudinal giant magnetic impedance effect of the core drive coil becomes more pronounced. When the cross-sectional area of the drive coil increases, the maximum impedance ratio (ΔZ/Z)max of the core drive coil decreases as a power function; when there is a power function relationship between the core filling factor and the maximum impedance ratio (ΔZ/Z)max of the core drive coil.
