Peculiarities of Transport, Resonance and Optical Properties of the Anion-Substituted Manganese Chalcogenides

Abstract:

The transport, resonance and optical properties of anion-substituted manganese chalcogenides MnSe_1-_xTe_x 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.
