Abstract

The fluctuation rate of Ce-4f moments in the paramagnetic phase of CeB₆ near zero field was determined by longitudinal muon spin relaxation. The rate scales perfectly with resistivity in the entire paramagnetic phase, indicating that the fluctuation is predominantly determined by the Kondo effect. The absence of magnetic order in the presumed antiferro-quadrupolar (AFQ) phase was also confirmed, while no evidence for coupling between the AFQ order parameter and electric field gradient at the B site was found near zero field by the muon nuclear level-crossing resonance technique.
