Dynamics of Field Induced Polarization Reversal in Strained Perovskite   Ferroelectric Films with c-oriented Polarization
  The field-induced polarization reversal in $c$-oriented ferroelectric phase of strained perovskite film has been studied. We show that in additional to the conventional longitudinal switching mechanism, when c-oriented polarization vector changes its modulus, the longitudinal-transversal and transversal mechanisms when the perpendicular component of polarization is dynamically admixed are possible. The later process can occurs either via the straight-abrupt or initially-continues polarization turnover scenario. We specified the obtained results for the case of PbTiO$_{3}$ and BaTiO$_{3}$ ferroelectrics and propose the experimental methods for their investigation.
