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