Ternary thallium lanthanide dichalcogenides TlLnX_{2} (X = S, Se, or Te; Ln = lanthanide, except Ce and Pr) crystallize in the rhombohedral structure of α-NaFeO_{2} type ($R\overline{3}m$). Their crystal lattice consists of the layers of Ln^{3+} ions separated by three layers of the non-magnetic ions (-Ln-X-Tl-X-Ln-). The magnetization was measured in the field range 0-14 T. The molecular field constants λ_{m} were estimated by fitting the Brillouin function to the experimental magnetization plots. The difference between the λ_{m} values for the thallium gadolinium sulphide and the selenide corresponds to the different character of Gd-S and Gd-Se bonds and gives rise to the different J_{1} and J_{2} exchange integrals.
