During the study of Bi2Te3-Sb2Te3 crystals, their magnetic and optical properties were studied depending on the ratios of the components of Bi2Te3 and Sb2Te3 in the composition of the solid solution and temperature. The results obtained allow us to state that a sharp decrease in the anisotropy of magnetic susceptibility at T = 293 K is observed in those samples in which, according to optical studies, electron-plasmon interaction is intensified, which is caused by the convergence of plasmon energies and interband transitions that form the fundamental absorption edge.
