Abstract

Muon spin rotation/relaxation measurements have been performed in the itinerant helical magnet MnSi at ambient pressure and at 8.3 kbar. We have found the following: (a) the spin-lattice relaxation rate [Formula presented] shows divergence as [Formula presented] with the power [Formula presented] larger than 1 near [Formula presented]; (b) [Formula presented] is strongly reduced in an applied external field [Formula presented] and the divergent behavior near [Formula presented] is completely suppressed at [Formula presented]. We discuss that (a) is consistent with the self-consistent renormalization theory and reflects a departure from “mean-field” behavior, while (b) indicates selective suppression of spin fluctuations of the [Formula presented] component by [Formula presented].
