Rezumat

The ternary iron chalcogenides, TlFeS2, TlFeSe2, RbFeSe2 consisting of linear chains of FeX4 (X=S, Se) tetrahedra, and Tl3Fe2S4 with zig-zag chains of FeS4 tetrahedra have been investigated by means of magnetic susceptibility, specific heat, Mössbauer, and ESR measurements. Single crystals of TlFeS2, TlFeSe2, RbFeSe2, and Tl3Fe2S4 exhibit three-dimensional collinear antiferromagnetic order with strongly reduced moments below 196K, 290K, 248K, and 90K, respectively. The magnetic moments are oriented perpendicular to the chain direction. Tl3Fe2S4 reveals a susceptibility maximum at Tmax = 435K, which is typical for one-dimensional antiferromagnetic spin chains, whereas RbFeSe2 and TlFeX2 (X = S, Se) exhibit a continuous linear increase of the susceptibility up to the highest measurement temperature (600K) suggesting 1D metallic character.
