概要
- 論文の詳細を見る
The itinerant helimagnet MnSi has been studied using NMR and susceptibilitytechniques above T.. The magnitude and temperature dependence of the "MnKnight shift K, quadrupole coupling vq and the nuclear spin-lattice and spin-spinrelaxation times Tg and T. have been determined along with new high temperaturemeasurements of the uniform susceptibility 740). Both K and v, are shown to beproportional to z(0), with temperature the implicit parameter. T. and T. aretemperature independent well above T. and their magnitudes cannot be explainedby the fluctuations of localized moments. The results of all of our measurementsare in general accord with the predictions of the renormalized RPA theory ofspin fluctuation phenomena in itinerant magnets of Moriya and his collaborators
