Weak ferromagnetic ordering in the anomalous field-insensitive heavy-fermion state in SmOs$$_4$$Sb$$_{12}$$

Zero field (ZF) and transverse field (TF) muon spin relaxation and rotation ($$mu$$SR) study has been carried out in filled-skutterudite SmOs$$_4$$Sb$$_{12}$$ in order to investigate the magnetically robust heavy-fermion (HF) state and the weak ferromagnetic anomaly. A large-amplitude oscillating signal appears in the ZF-$$mu$$SR spectra at low temperatures, confirming that the weak ferromagnetic anomaly is an intrinsic bulk property. Analysis reveals that the weak ferromagnetic moment is carried by itinerant heavy quasiparticles.
