本文报道了用气体雾化法制备的软磁Co_（36）Fe_（36）B_（19）Si_（55）Nb_4金属玻璃纳米/微米线的磁阻抗测量结果。导线阻抗随外部磁场而变化，阻抗峰值位置取决于频率，表明铁磁共振。铁磁共振中各向异性方向的假设允许确定导线中的磁各向异性。通过减小导线直径，观察到磁各向异性的减小。(C)2014年作者。除非另有说明，否则所有文章内容均根据Creative Commons Attribution 3.0 Unported License许可。
We report the magneto-impedance measurements in soft-magnetic Co36Fe36B19Si5Nb4 metallic glass nano/micro wires produced by gas atomization. The wire impedance varies with external magnetic fields and the impedance peak position depends on the frequency, indicating ferromagnetic resonance. The postulation of anisotropy directions in ferromagnetic resonance allows to the determination of magnetic anisotropies in the wire. By decreasing the wire diameter, the reduction of magnetic anisotropy is observed. (C) 2014 Author(s).
