| 摘 要： | 对于软磁材料，用振动样品磁强计测量其基本磁性参数时，因饱和时的外加磁场远大于软磁材料饱和时的矫顽力，常常会因测量饱和磁化强度Ms而不能保证测量矫顽力Hc的一定精度。文章提出应用非均匀磁场扫描的方法实现饱和时的饱和磁化强度Ms和矫顽力Hc的精密测量。

| Abstract: | While some basic magnetic parameters for a sort of soft materialsare detected by means of vibration sample magnetometer，it is impossible that high resolution of the coercivity under the condition of saturation magnetization is attained because to the state of saturation magnetization for soft magnetic materials the applied magnetic field Hmaxtheir coercivity HC．Hence，this paper presents a high resolution measurement of the coercivity and saturation magnetization using a method of non-uniformity scanning magnetic field． |
