Abstract:
Results of an experimental study of MnS, FeS, and Fe x Mn1−x S single crystals are presented. The phase composition, the lattice parameters, and the state of paramagnetic ions in Fe x Mn1−x S have been determined by x-ray diffraction analysis and Mössbauer spectroscopy. A sequence of transitions have been found in iron manganese sulfide with x = 0.29 at temperatures T 1 ≈ 25–50 K, T 2 ≈ 125 K, and T 3 ≈ 190 K with a change in kinetic properties and the formation of a metallic state at low temperatures T ≈ 2 K. The possibility of a Mott-Hubbard transition in Fe x Mn1−x S sulfides with variation of the composition and the temperature is discussed.
