Electron spin resonance in disordered metals.
01 January 1986
A theoretical study of the spin resonance signal of electrons in a disordered metal with magnetic impurities is performed. It is found that there are singular corrections to the linewidth near two dimensions. These corrections arise both from disorder and from the disorder enhanced electron-electron interactions. To lowest order in the triplet scattering amplitude, the increase in linewidth is simply related to the enhancement of the spin susceptibility. These results are in agreement with recent experiments.
