The magnetic moment of Sm{sup 3+} in hcp Sm was studied with a magnetic Compton-scattering experiment with the aid of a pulse magnet. We have successfully obtained direct evidence for a positive contribution of the spin moment to the total moment, opposite to the case for a free ion. The enhancement of the spin moment by incorporation of the conduction electron polarization is observed. {copyright} {ital 1997} {ital The American Physical Society}
