Abstract
In this work we present a magnetoresistance study on the CeRu2Ge2 compound. We analyze the rho(T) curves for several applied magnetic fields using the electron-magnon scattering model for a ferromagnetic spin arrangement. Fro m this analysis, the field dependence of the energy gap of the magnon spect rum is obtained. The magnetoresistance rho(H) at various temperatures arise s from a normal metal contribution with an additional scattering mechanism due to electron-magnon interaction.
