Abstract

μ SR study on the anomalous magnetic behavior of an intermetallic superconductor Mo₃Sb₇ is reported. Muon depolarization rate due to dynamically fluctuating electronic spins is reduced with decreasing temperature, which is in line with the development of a spin-liquid state. Meanwhile, the detailed analysis of structural deformation below 50 K suggests that the presumed spin-gap is not fully opened, and that the magnetic state just above T_c might be understood as an itinerant paramagnetic state with localized spin-singlets.
