Abstract: The temperature dependences of the magnetic susceptibility of crystals of solid solutions of Bi2Te3-Sb2Te3 p – type conductivity containing from 25 to 70 mol. percent of antimony telluride obtained on a SQUID magnetometer MPMS (Magnetic Property Measurement System) MultiVu in the range from 2 to 400 K. A correlation was found between the features observed in the behavior of the temperature dependences of the magnetic susceptibility of crystals containing 60 and 70 mol. percent Sb2Te3 and the ratio of the plasmon energy to the gap energy between the chemical potential level and the heavy hole subzone. The assumption is formulated that in the case of convergence of these energies, the increasing electron-plasmon interaction affects the state of the electronic system, and thus the magnitude of magnetic susceptibility.
