The nuclear magnetic resonance of Pt^<195> in dilute magnetic PtCr alloys was observed at the temperature of 4.2K and 1.5K. The linear decrease of the nagative Knight of Pt^<195> versus Cr impurity concentration was observed and found to be slightly temperature dependent. The nagative host polarization by addition of Cr impurity was found by the magnetic susceptibility measurement and this negative polarization due to Cr impurity slightly increases with the decrease of temperature. These results were qualilatively interpreted by the decrease of the effective s conduction electron density and the relation of the reduction of s conduction electron density to the formation of s-d bound state was examined. Also the magnetic susceptibility of PtMo alloys is reported in connection with the Pt^<195> Knight shifts in this alloy which were previously reported by Weissman and Knight. The results of thermo-electric power of PtCr alloy are also given.
