Abstract
Proton NMR Knight shifts are measured in the paramagnetic state of RH2 (where R = Pr, Nd, Sm, Gd, and Tb). The data are interpreted in terms of the effective hyperfine field at the proton site, being equal to −16.7 × 104 A/m for the Pr, Nd, Gd, and Tb dihydrides and −7.96 × 104 A/m for SmH2. The temperature dependence of the magnetic susceptibility in SmH2 is also measured. The anomaly observed at 9 K is attributed to antiferromagnetic ordering. Analysis of the susceptibility data indicates that SmH2 is the Sm3+ compound.Keywords
