Neutron-diffraction study in TlFeS2 and TlFeSe2 at low temperatures

The crystal and magnetic structures of TlFeS 2 and TlFeSe 2 are studied by neutron diffraction in the temperature range of 10–320 K. The structures of TlFeS 2 and TlFeSe 2 have monoclinic symmetry with the space group C 2/ m at room temperature. TlFeS 2 displays an antiferromagnetic phase at tempera...

Description
Summary:The crystal and magnetic structures of TlFeS 2 and TlFeSe 2 are studied by neutron diffraction in the temperature range of 10–320 K. The structures of TlFeS 2 and TlFeSe 2 have monoclinic symmetry with the space group C 2/ m at room temperature. TlFeS 2 displays an antiferromagnetic phase at temperature below 200 K. The antiferromagnetic phase transition in TlFeSe 2 takes place at a temperature below 290 K. The temperature dependence of the unit-cell parameters and volume are obtained. The coefficients of thermal and linear expansion are calculated. The temperature dependences of the interatomic distances are presented.
