Magnetization Density Distibution in U(2)Co(2)Sn
A magnetization density study by polorized-neutron scattering on the intermetallic compound U(2)Co(2)Sn is reported. U(2)Co(2)Sn belongs to large An(2)T(2)X (An=U,Np, Pu,Am, T=transition metal, X=In, Sn) family of compounds crystallizing in an ordered variant of the tetragonal U(3)Si(2) type of structure (space group P4/mbm).U(2)Co(2)Sn does not order magnetically but has a large magnetic susceptibility that qualifies it as an enhanced paramagnet or spin fluctuator. We report single-crystal magnetization measurements that show an important magnetic anisotropy, with a c-axis susceptibility exceeding that measured on the basal plane by a factor of four. The magnetization density distribution in the unit cell was measured at 2 K by polarized neutron scattering under a magnetic field of 5.5 T applied parallel to the c-axis. It was found that the major contribution to the magnetic susceptibility is located on the U atoms (u=118(3)mB) but a small response from the Co atoms is also measured (Co = 13(2)mB).
