We report novel phase transition at similar to 0.9 K in the Ce-based filled-skutterudite compound CeOs4Sb12 via the measurements of nuclear-spin-lattice-relaxation-rate 1/T-1 and Sb-123-NQR spectrum. The temperature (T) dependence of 1/T-1 follows 1/T-1 proportional to (T-theta)(1/2) with theta = 0.06 K in the range of 1.3 K < T < 25 K, suggesting that the system is close to an antiferromagnetic critical point. The onset of spin-density-wave (SDW) order at T-SDW similar to 0.9 K is evidenced by the broadening of NQR spectrum and marked reduction in 1/T-1 just below TSDW: (C) 2003 Elsevier B.V.
