Abstract
The U2Ni2Sn stannide has been studied by means of neutron powder diffr action and Mossbauer spectroscopy. This compound crystallizes in the t etragonal P4/mbm space group in an ordered version of the U3Si2-type s tructure and orders antiferromagnetically below T-N = 25(1) K. At T = 1.5 K the magnetic structure is collinear with uranium magnetic moment (1.05(5)mu(B)) perpendicular to the tetragonal c-axis. Sn-119 Mossbau er spectroscopy at 4.2 K shows that tin atoms see a zero hyperfine fie ld, in agreement with the proposed antiferromagnetic order.
