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 Bi0.6Sb1.4Te3 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.
