Abstract

In the intermediate valent compounds Ce x La1−xOs2 the Gd3+-ESR shows a non-linear increase of the linewidth ΔH(T) in the temperature range 4.2K<T<300K for 0.3≦x≦1.0. This non-linearity of the thermal broadening is strongly altered by changing the Ce-concentration. The experimental results ΔH(T,x) can quantitatively be described via hybridization of conduction electrons with Ce4f electrons: Due to hybridization, the Ce4f states are broadened but remain localized. The conduction electron density of states is reduced in the vicinity of the 4f states. In addition we observe a maximum in the electrical resistivity ϱ(T) of CeOs2 at 270 K.
