Аннотация: Electrical resistivity of the FeXMn1−XS (0 ≤ X ≤ 0.29) single crystals based on the Mott insulator α-MnS is experimentally studied in the temperature range of 2–300 K at ambient pressure (P = 0) and at high (up to 30 GPa) hydrostatic pressures for x = 0.12. The electron subsystem of FeXMn1−XS undergoes insulator-to-metal transitionПоказать полностьюs indicated by a resistivity drop by a factor of 106 with an increase in the chemical pressure (X) due to the cation substitution under ambient conditions and at the hydrostatic pressure (PC = 27 ± 5 GPa) for x = 0.12. The results obtained show that the hydrostatic pressure - and cation-substitution induced insulator-to-metal transitions in the α-MnS-based Mott compounds have similar mechanisms. The dependence of the critical hydrostatic pressure PC on the Fe content in FeXMn1−XS is established. © 2018 Elsevier B.V.
