Abstract

We report the first 139 La-NMR measurements on a La dilute system of PrPb3. We have succeeded to detect 139La-NMR signal on a powder sample of Pr0.97La0.03Pb3 and extracted the temperature dependence of the Knight shift139 K(T) in a temperature range between 1.5 and 220 K. K(T) has been found to maintain a linear relation with the bulk-susceptibility χ(T)bulk in wide temperature range, except for a small deviation in the temperature region below 6 K. The slopes of the139 K vs ν bulk plots yield for the hyperfine coupling constants Ahf the value 375 Oe/μβ. From the NMR results, we discuss the effect of the La substitutions on microscopic magnetic properties of PrPb3.
