Transmission Electron Spin Resonance Investigations in Aluminium

Abstract

Conduction electron spin resonance transmission in aluminium has been observed at a frequency of 22.6 GHz under the completely damped spin-wave condition. Line shape fittings based on two TESR theories have been performed. The theory of Walker has turned out to explain fairly well the data in the anomalous skin effect condition at 18 K. The probability ε of a spin flip at the surface has been found to be about 1×10⁻³, which is in good agreement with that obtained from the reflection measurement. DC resistivity in the same samples has also been measured. The applicability of several TESR theories has been considered, referring to the skin effect condition, g anisotropy and electron-electron interaction.
