Different temperature dependence of the 55Mn Knight shift has been observed for each Mn atom at four inequivalent crystallographic sites in α-Mn metal. These characteristic properties are tried to understand by the phenomenological localized spin fluctuation model, where the effect of spin fluctuation is considered by the same procedure established in the Kondo problem and the exchange interaction between magnetic moments is approximated by the molecular fields, The experimental results of the Knight shift and the anomalous transport properties of α-Mn are found to be qualitatively well understood by this phenomenological model. The existence of the localized spin fluctuations in α-Mn, postulated previously by the XPS measurements, is confirmed.
