通过纵向μ子自旋弛豫测定了CeB 6 顺磁相近零场的Ce-4f矩涨落率。该速率与整个顺磁相中的电阻率完美地成比例，表明波动主要由近藤效应决定。还证实了假定的反铁四极（AFQ）相中不存在磁序，而μ子核穿越共振技术在零场附近没有发现AFQ序参数与B位电场梯度之间存在耦合的证据。
The fluctuation rate of Ce-4f moments in the paramagnetic phase of CeB 6 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.
