Abstract: We have investigated the spin dynamics of the paramagnetic region of epsilon-FeGe by means of Electron Spin Resonance (ESR) spectroscopy. The high-quality single crystal showed a strong paramagnetic resonance line which is well-described by a Lorentzian shape above 287 K. The close relation of the linewidth to the magnetic susceptibility indicates a resonance of a strongly coupled 3d / conduction electron system.
