摘要: We report on μSR studies in low charge carrier density heavy‐fermion systems with cubic symmetry. Whereas for Ce3Au3Sb_4 and Sm3Te4 the data point to presence of some kind spin‐glass‐like magnetic states at temperature, Yb4As3 preliminary just show a slight increase depolarization rate which indicates slowing down Yb‐moment fluctuations. Consequently this latter system, large linear term specific heat seems indeed be connected electronic excitations.
