| 摘 要： | 分别利用分形理论和电子自旋波角分布场理论研究了磁性超微粒的超顺磁化特性,并且导出了两个理论公式.理论计算模拟得到的超微粒磁化曲线与Shunji bandon等人实验测得的磁化曲线相符合,有效地解释了超微粒与块状材料之间磁化特性差异.

| Abstract: | By using the fractal theory and angular distribution theory of electron spin-wave, the super-paramag-netism of ultrafine particles were researched, and two theoretical formulas of magnetization were derived. The magnetization curves modeled after theoretical calculations are consistent with the experimental-magnetization cutves which was measured by Shunji Bandon et. al. It is satisfactory to explain the difference of magnetization properties between ultrafine 'particles and bulk material. |
