Analysis for Magnetization of Ce1-xRxFe2 (R= Pr, Nd) Based on NMR Study

We have carried out 141 Pr and 143 Nd NMR measurements on Ce 1- x R x Fe 2 (R = Pr, Nd) at 1.4 K. The hyperfine fields of Pr and Nd remain nearly constant in the measured concentration ranges: 0.15 ≦ x ≦0.43 and 0.1 ≦ x ≦0.4 for Pr and Nd compounds, respectively. The hyperfine fields analysis combining with 57 Fe Mossbauer effect results give the magnetic moments of Pr and Nd in the compounds to be about 2.6 µ B and 2.8 µ B , respectively. The magnetizations of Ce 1- x R x Fe 2 are estimated and discussed.
