We report on the muon spin rotation/relaxation study of a pyrochlore oxide, Cd_2Os_2O_7, which exhibits a metal-insulator (MI) transition at T_<MI>[〜!-]225K without structural phase transition. It reveals strong spin fluctuation ([>!-]10^8s^<-1>) below the MI transition, suggesting a predominant role of geometrical spin frustration amongst Os^<5+> ions. Meanwhile, upon further cooling, an incommensurate spin density wave discontinuously develops below T_<SDW>[〜!-]150K. These observations strongly suggest the occurrence of an anomalous magnetic transition and associated change in the local spin dynamics in undistorted pyrochlore antiferromagnet.
