摘要

本文研究了室温下自由镦粗变形的富勒石粉体的晶体结构变化、磁性和谐振性的变化。通过对所发现的x射线反射展宽的比值的分析,认为展宽是由微应力引起的,具有相当大的价值。根据ESR的研究数据,提出了碳原子在变形过程中由于机械损伤而产生的价键断裂是导致所观察到的磁性变化的原因。

Influence of processing C60 fullerite by pressing on its crystalline structure and magnetic properties
In the current work the changes in a crystalline structure and the change of magnetic and resonant properties occurring in the powder of fullerite, deformed under conditions of free upsetting at room temperature have been investigated. The analysis of the ratio of the discovered broadening of x- ray reflexes allows believing that broadening is caused by microstresses, which have rather a great value. According to ESR research data the supposition has been made that torn off valence bonds of atoms of carbon, which appear because of mechanical damages under the deformation, are responsible for the changes of magnetic properties observed.
