研究了磁场对纵向磁场控制下电镀镍铜复合导线磁性能的影响。在0 ~ 400 Oe的纵向磁场作用下，制备了20 μm直径的镀有一层Permalloy™（Ni80Fe20）的铜复合丝样品，并对其显微组织和磁性能进行了测量。结果表明：复合丝镀中的纵向磁场使镀层中晶体的排列更加有序，从而提高了镀层材料的均匀性和磁性柔软度；使镀层的磁各向异性由周向向纵向转变，提高了镀层复合丝在磁阻抗效应测试中的临界频率，此时磁阻抗比达到最大值。
The effect of the magnetic field on the magnetic properties of NiFe/Cu composite wires electroplated under a longitudinal magnetic controlling field is presented. Composite wire samples of 20-μm-diameter Cu electroplated with a layer of Permalloy™ (Ni80Fe20) under the influence of a longitudinal magnetic field of intensities ranging from 0 to 400 Oe were produced, and the microstructure and magnetic properties were measured. The results showed that the longitudinal magnetic field in the composite wire plating makes the packing of the crystals in the plated layer more orderly, and thus increases the uniformity and magnetic softness of the plated material. It also shifts the magnetic anisotropy of the plated layer from circumferential to longitudinal, and increases the critical frequency of the plated composite wire in magnetoimpedance effect testing, at which the magnetoimpedance ratio reaches the maximum.
