Abstract

We have investigated the spin dynamics of the paramagnetic region of ##IMG## [http://ej.iop.org/icons/Entities/epsilon.gif] {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 3 d / conduction electron system.
