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 Pr_0.97La_0.03Pb₃ 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 A_hf the value 375 Oe/μβ. From the NMR results, we discuss the effect of the La substitutions on microscopic magnetic properties of PrPb₃.
