Size effect on the fundamental properties of Sn₂P₂S₆ ferroelectric is studied. The decrease of Raman peak frequency, accompanied by the band broadening and asymmetry, is observed in the spectra of microcrystalline Sn₂P₂S₆ powder. Theoretical calculations, performed in the ANNNI model for Sn₂P₂S₆...
