We report measurements of the magnetic susceptibility, specific heat, magnetoresistance, Hall effect, and Fermi surface in SmCu{sub 6}. The susceptibility follows the Van Vleck form for Sm{sup 3+} near room temperature and shows two antiferromagnetic phase transitions at 9.6 and 5.2 K. The specific heat implies a quartet ground state for the crystal-field-split {ital J}=5/2 angular momentum state. Magnetoresistance indicates that SmCu{sub 6} contains both electron and hole carriers but is uncompensated. de Haas--van Alphen measurements show that the Fermi surface in the antiferromagnetic state consists of a network of cylinders oriented 30{degree} from the {ital b} and {ital c} axes.
