• Magnetic susceptibility and NMR measurements on Pt with addition of 3d,4d and 5d transition metal solutes were carried out at helium temperature tostudy the effect of nonmagnetic and magnetic solutes on the magnetic propertiesof Pt. The change of the host d band susceptibility and its valence number depend-ence were obtained and compared with the theory by Asano et al. for nonmagneticsolute alloy. From this comparison, it was concluded that the change of the hostd band susceptibility arises from the change of the density of states at E. of Pt.As for magnetic alloys, it was found that the effect due to the polarization ofconduction electrons by the localized magnetic moment of solute is predominantin the alloys with low T, (PtCo, PtFe), whereas in the alloy with high 7'. (PtCr),the same mechanism as that of nonmagnetic alloy becomes important.
