We have applied 149Sm nuclear forward scattering of synchrotron radiation to study the properties of the Sm sublattice in SmAl 2. A self-consistent analysis of the neutron magnetic form factor together with the thermal variation of the 149Sm hyperfine interaction parameters and of the bulk magnetization was carried out. This enabled us to refine the crystal field and exchange parameters and to deduce the temperature dependence of the 4f magnetic moment and of the conduction electron polarization.
