Abstract
Off-stoichiometric manganese monosulfides α-MnxS (1≤x≤1.25) are synthesized, and their crystal structure and magnetic properties are studied in the 4.2-to 300-K range. The compounds have a NaCl fcc lattice. Increasing the manganese ion concentration x in the antiferromagnetic semiconductors α-MnxS is found to result in concentration-(x c ∼ 1.05) and temperature-driven (T c ∼ 50 K) magnetic transitions from the antiferromagnetic to ferromagnetic state, with the cubic structure remaining unchanged.
