Abstract:

© 2017, Allerton Press, Inc. Single crystals of ternary ion chalcogenides RbFeSe 2 , TlFeSe 2 , and TlFeS 2 are studied by X-ray diffraction, SQUID magnetometry, and Mössbauer spectroscopy. Common structural units of these chalcogenides are tetrahedra of FeCh 4 (chalcogen Ch = Se, S), arranged in chains by sharing an edge. It is found that RbFeSe 2 , TlFeSe 2 , and TlFeS 2 undergo transition to a collinear antiferromagnetic state below temperatures T N = 248, 290, and 196 K, respectively. Their magnetic moments are oriented perpendicular to the axes of the chains of FeCh 4 tetrahedra.
