Single-Crystal Magnetization and Neutron-Scattering Investigation of the Magnetic Structure of U2Rh2Sn
U2Rh2Sn is a member of a large family of intermetallic compounds with the tetragonal U3Si2 crystal structure. It orders antiferromagnetically at 28K with the propagation vector k = (0,0, 1/2). We have performed magnetization and neutron-scattering experiments on a single 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)nB. This is considerable reduced from the free ion value for both U3+ and U4+ configurations and suggests that the f-electrons are strongly hybridized with the conduction band.
