U(2)Rh(2)Sn is a member of a large family of intermetallic compounds with the tetragonal U(3)Si(2) crystal structure. It orders antiferromagnetically at 28K with the propagation vector k equals (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 Gamma(8) 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 0.53(2)mu(B). This is considerable reduced from the free ion value for both U(3+) and U(4+) configurations and suggests that the f-electrons are strongly hybridized with the conduction band.
