| Popis: | U2Pt2Sn is crystallizing in an ordered version (space group P42/mnm) of the tetragonal U3Si2 type of structure. Clear anomalies in the magnetic susceptibility, specific heat, and electrical resistivity around 15 K indicate that U2Pt2Sn orders antiferromagnetically below this temperature. As expected for an antiferromagnet, the susceptibility and specific heat anomalies are shifted to lower temperatures upon application of external magnetic field. The specific‐heat coefficient γ=327 mJ/mol f.u. K2 remains unchanged in fields up to 5 T. The antiferromagnetic ground state of U2Pt2Sn can be concluded also from the metamagnetic transition around 22 T in the magnetization at 4.2 K and from magnetic reflections in the neutron‐diffraction pattern at low temperatures. |
