| Abstract: | Electron spin resonance line width of colloidal sodium conduction electrons in sodium azide has been investigated as a function of temperature. The width varies approximately linearly with temperature from 77°K to the melting point of sodium (371°K) with a slope of 0·027 G/deg. An abrupt change in the resonance width occurs at the melting point of sodium. From the melting point to 475 °K the curve is almost linear with a slope of 0·041 G/deg. It can be shown that the data is in good agreement with the idea that the width of the resonance is proportional to the resistivity. This work extends the range of previous data to higher temperatures. |
