 Abstract: The evolution of the electronic density of states at the Fermi level of intermetallic EuFe2-xRuxAs2 in the whole concentration range ( 0 <= x <= 2) is reported. Systematic electron spin resonance investigations of the Korringa-type Eu spin relaxation in combination with the results of band-structure calculations and magnetic susceptibility measurements can provide a clear picture of how the density of states is reduced by substituting Fe with Ru in EuFe2As2. Moreover, the strength of the exchange coupling between the local Eu and the itinerant spin systems can be estimated consistently with the weak coupling expected for this class of layered compounds.
