The temperature dependences of the hyperfine field and the spin-lattice relaxa-tion time T. at the interstitial p" sites in the helically ordered state of MnSi havebeen measured by the longitttdinal z'SR technique. The hyperfine field at 4.2 Kis found to be -(l.55f0.05) k0e which is 17'/. snaaller than that expected fromthe hyperfine coupling constant in the paramagnetic :state A..= -4.8 kOe/q. andthe ordered moment of 0.39 jt?/Mn. The temperatture dependence of the relaxa-tion rate 1/T. shows an intermediate character between weakly ferromagneticautd antiferromagnetic metals based on the self-consi:stent renoruaaalization (S(OR)theory of spin fluctuations. This fact is in contrast 1.o the observed tempera'Luredependence of J /T. in the paramagnetic state which is in general accord with theprediction of the SCR theory for weakly ferromagnetic metals.
