Is UPtSn a Nonmagnetic Semiconductor or a Metallic Antiferromagnet?

  • Published:
Czechoslovak Journal of Physics Aims and scope

Abstract

Magnetic and electrical resistivity measurements reported in literature had not provided a definite answer to the question posed in the above title. In the present paper we shall argue, on the basis of the electronic band structure calculations, that the stable ground state of UPtSn is a metallic antiferromagnet. In the antiferromagnetic state the total energy is by about 0.1 Ry (per formula unit) lower than the one for the paramagnetic state and by about 1.2 Ry for the (hypothetical) ferromagnetic state.
