Description of lattice anharmonicity observed in ferroelectrics with unusual three-well local potential
For Sn₂P₂S₆ family of uniaxial ferroelectrics, the anharmonic quantum oscillators model, based on local threewell potential for spontaneous polarization fluctuations, has been used for a description of anharmonic properties, namely thermal expansion. The calculated pseudospin fluctuations spectra i...
