Abstract: The temperature dependences of the reflection coefficient spectra in the range of effects caused by the resonant behavior of the plasma of free charge carriers of the Bi$_{0.6}$Sb$_{1.4}$Te$_3$ crystal, in the temperature dependences of the magnetic susceptibility of which features are observed, are investigated. A change in the shape of the plasma edge and the resulting splitting of the peak of the energy loss function were detected, which allows us to conclude that an electron-plasmon interaction affecting the state of the electronic system has been observed.

Keywords: bismuth and antimony tellurides, plasma reflection, plasmon, electron-plasmon interaction.
