Field dependence of the muon spin relaxation rate in MnSi

New sets of μSR measurements in MnSi are presented and the effect of the applied field on the critical behavior observed via the relaxation rate 1/T1 are presented. As such, a departure of 1/T1 from the linear behavior T1Tα(T-Tc) is found and confirmed the very small pressure dependence of the magnetic moment in the ordered phase.
