Antiferromagnetic fluctuations in CePdSn Kondo compound from Mössbauer spectroscopy

119Sn Mossbauer spectroscopy was used to study the fluctuations of antiferromagnetic domains in the heavy-fermion CePdSn Kondo compound. The temperature evolution of the experimental spectra was described within both two- and multi-level relaxation models. The difference between these two approaches is discussed. The temperature dependence of the relaxation rate of the domain’s magnetization and the density of itinerant electrons near the tin atoms are investigated.
