Electronic properties of U{sub 2}Pt{sub 2}Sn

PDF Version Also Available for Download.

Description

U{sub 2}Pt{sub 2}Sn is crystallizing in an ordered version (space group P4{sub 2}/mnm) of the tetragonal U{sub 3}Si{sub 2}-type of structure. Clear anomalies in the magnetic susceptibility, specific heat and electrical resistivity around 15 K indicate that U{sub 2}Pt{sub 2}-Sn 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 {gamma} = 327 mJ/mol f.u. K{sup 2} remains unchanged in fields up to 5T. The antiferromagnetic ground state of U{sub 2}Pt{sub 2}Sn can be concluded also from the metamagnetic transition ... continued below

The antiferromagnetic ground state of U{sub 2}Pt{sub 2}Sn 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.
