Abstract:

The dependence of the character of the phase transition that accompanies the polaron band collapse in Ag-x TiTe2 on the concentration of polaron centers determining the density of states of the polaron band was studied by differential thermal analysis and by measuring the magnetic susceptibility. In the low-concentration limit, the transition is found to be smooth. As the concentration of impurity centers increases, the transition changes to the first order. On the temperature-concentration diagram, the line along which the change in the phase transition order occurs is determined by percolation laws. It is shown that the thermal effect accompanying the transition can be related to the decrease in the electron free energy due to polaron localization.
