Abstract
TlMnS2 and TlMnSe2 crystals have been synthesized by the method of solid-state reaction from chemical elements weighted in the stoichiometric ratio. X-ray, magnetic, and electric studies have been performed. It is established that the TlMnS2 compound crystallizes in the tetragonal structure with the unit-cell parameters a = 7.74 Å, c = 30.60 Å, Z = 20, and ρx = 6.40 g/cm3; TlMnSe2 crystallizes in the hexagonal structure with the unit-cell parameters a = 6.53 Å, c = 23.96 Å, Z = 8, and ρx = 6.71 g/cm3. TlMnS2 and TlMnSe2 are semiconductors and exhibit an antiferromagnetic character of exchange interaction.
