“…The dependence of the magnetic susceptibility on the prehistory of the sample indicates a possible dependence of the magnetic susceptibility on the magnetic field. In our recent work [14], we revealed the peak of the magnetization at the temper ature T = 260 K in the magnetic field H = 0.05 T for the MnSe compound, which is probably attributed to the formation of a hexagonal structure and the coex istence of two crystalline structures. This maximum disappears upon the anion substitution, and only a sin gle broad maximum is observed in the temperature range T = 100-180 K. 4.…”

The anion substituted solid solutions of the MnSe 1 -x Te x system have been synthesized. The crys tal structure and magnetic properties of the synthesized solid solutions have been investigated. It has been shown that, in the concentration range 0 ≤ x ≤ 0.4, the solid solutions have a face centered cubic structure. It has been revealed that an increase in the concentration of the substituting element in the MnSe 1 -x Te x system leads to an increase in the coefficient of thermal expansion of the sample. The investigation of the magnetic properties has been carried out at temperatures in the range 80 K < T < 1000 K in a magnetic field up to 8.6 kOe. It has been experimentally found that the type of antiferromagnetic order (the second type of order ing) remains unchanged over the entire concentration range up to x = 0.4 and that the paramagnetic Curie temperature and the Néel temperature decrease within the limits of 20%. Theoretical calculations have been performed using the Monte Carlo method, and the model of nanoclusters with an uncompensated antiferro magnetic moment has been proposed.

“…The manganese monoselenide MnSe has a p-type conductivity. For small substitution concentrations X = 0.1, with increasing temperature (figure 2a), the Hall coefficient (RH) increases and at a temperature of 140K the sign of the Hall constant changes in the field where the maximum magnetoresistive effect is observed [25]. In the temperature range 140-347K, the hole type of 1230 (2022) 012016 IOP Publishing doi:10.1088/1757-899X/1230/1/012016 4 conductivity dominates with a sharp decrease in the RH at T = 320K.…”

The effect of anionic substitution on the structural, magnetic, and kinetic properties of chalcogenides of the MnSe1-XTeX system in the temperature range of 77-400K in magnetic fields up to 12 kOe was studied. With an increase in the substitution concentration, changes in the structural and magnetic characteristics, which correlate with changes in the electronic structure, were found. The type and mobility of the main current carriers were determined from the Hall effect measurements.

The transport, resonance and optical properties of anion-substituted manganese chalcogenides MnSe1-xTex in the 77-300 K temperature range in magnetic fields up to 1T are studied. The magnetoresistance effect with the maximum value in the vicinity of the Neel temperature for the composition x = 0.1 is revealed. EPR data indirectly indicate the type of the current carriers – lattice polarons. The changes in electron structure occurring due to the anionic substitution are studied using the optical methods.
