The second order phase transition in Sn<sub>2</sub>P<sub>2</sub>S<sub>6</sub> crystals: anharmonic oscillator model

Statistical theory for ferroelectrics based on triple well anharmonic potential was used for the case of structural second order phase transition in Sn<sub>2</sub>P<sub>2</sub>S<sub>6</sub> crystals. Parameters of effective Hamiltonian of the model were estimated...
