Вплив флексозв’язку та електрострикції на дисперсію м’яких фононних мод та розсіяння нейтронів в сегнетоелектриках
Within the Landau–Ginzburg–Devonshire (LGD) theory framework, the impact of the flexocoupling and electrostriction on the soft phonon dispersion and neutron scattering spectra is analyzed, and analytical expressions are derived. The impact of the higher gradient term in the LGD functional is studied...
