Localized Susceptibility and Spin Fluctuations in α-Mn by N.M.R. I

Abstract

NMR studies of α-Mn metal have been carried out in the paramagnetic phase between Néel temperature and room temperature. Different temperature dependence or the Knight shift has been observed for each Mn atom at four inequivalent crystallographic sites and a maximum of the Knight shift has been found from the resonance line for site I. Temperature dependence of the quadrupole interaction parameters has been determined from the resonance line for site III and site IV.
