摘要

通过对表面氧化的超细铁微粒的穆斯堡尔研究

确定了表面氧化层的德拜温度

改进了计算氧化层厚度的方法

得到了表面氧化层与核心α—Fe无反冲分数的比值随温度的变化关系.

Abstract

Small iron particles with oxide surfance layer were studied by Mossbauer spectroscopy at temperatures ranging from 5K to 300K. The Debye temperature of the oxide layer and the temperature dependence of f2/f1 were obtained

where f1 and f2 are the recoilless fractions for the inner α-iron core and the oxide layer respectively. Furthermore

the method of estimating thickness of the oxide layer was improved.
