摘要：

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. © 1990.
