摘要
含有纳米晶带的电感线圈与电容组成LC串联电路有固有谐振频率。通过实验研究了含有Fe基纳米晶带的电感线圈与电容串联电路谐振频率随外磁场变化的关系,讨论了磁致频移现象的原因。通过实验还研究了含有Fe基纳米晶带的电感线圈与电容串联电路在谐振频率的交变电流驱动下的巨磁阻抗效应。
There is the inherent resonant frequency that LC series circuit composed of a capacitor and a coil which containing nanocrystalline ribbons.The dependence of the LC series circuit resonant frequency on external magnetic field was measured and the reason of magnetic frequency shift was discussed.The giant magneto-impedance effect of the LC series circuit composed of a capacitor and a coil which containing nanocrystalline ribbons was investigated.
