is a member of a large family of intermetallic compounds with the tetragonal 
crystal structure. It orders antiferromagnetically at 
with the propagation vector k = (0,0,1/2). We have performed magnetization and neutron scattering experiments on a single crystal that show that the uranium atoms order in the collinear 
irreducible representation of the magnetic group, with the moments aligned parallel to the unique tetragonal axis. The value of the ordered magnetic moment of the uranium atoms refined from the neutron scattering intensities is 
. This is considerably reduced from the free-ion value for both 
and 
configurations and suggests that the f electrons are strongly hybridized with the conduction band.
