Abstract
- Mossbauer studies on a mosaic of single crystals of the layered compound TlFe 2− x Se 2 have been carried out at various temperatures between 100 and 460 K. A magnetic transition occurs at ∼450 K. The magnetic ordering within the FeSe layers is antiferromagnetic with the spins oriented along the tetragonal axis. X-Ray diffraction data indicated ordering of the iron vacancies at the chosen composition ( x ∼ 0.3) yielding a supercell with a volume five times that of the ThCr 2 Si 2 type subcell, the cell parameters being a = 8.6909(5) A and c = 14.005(1) A.
