We report on magnetic and novel superconducting properties in heavy-fermion (HF) noncentrosymmetric compound CePt3Si via the measurement of Pt-195 nuclear spin-lattice relaxation rate 1/T-1. This compound reveals the uniform coexistence of antiferromagnetism (T-N = 2.2 K) and superconductivity (T-c =0.75 K). CePt3Si is the first HF superconductor that reveals a peak in 1/T-1 just below T-c and, additionally, does not follow the T-3 law that was observed for most unconventional HF superconductors. The novel relaxation behavior found below T-c may be relevant with a possible novel SC state being realized in the noncentrosymmetric CePt3Si. (c) 2005 Elsevier Ltd. All rights reserved.
