文摘

We report on detailed longitudinal field (LF) muon spin relaxation studies in SmRu₄P₁₂ in order to characterize magnetic fluctuations in a magnetically ordered state below . The magnitude and fluctuation rate of the fluctuating field are derived as functions of temperature from LF dependence of the longitudinal relaxation rate. Possible low-energy excitations of magnetic multipoles are discussed.
