热退磁磁体的初始磁化率χ远高于场退磁磁体的初始磁化率χ。具有降低的结晶度的样品显示增加的χ值。这和最大外加磁场的依赖性解释了空间场波动对磁化强度变化的影响。
The initial susceptibility χ of thermally demagnetized magnets is much higher than that of field demagnetized magnets. Samples with reduced coercivity show incresed values of χ. This and the dependence of coercivity on maximum applied field are explained by the influence of spatial field fluctuations on magnetization change.
