Longitudinal and transversal polarization switching in strained ferroelectrics

Résumé

Using the multicomponent Landau-Devonshire functional we study the field-induced polarization switching in c-oriented ferroelectric phase of epitaxial perovskite film and found that two different regimes are possible: (i) longitudinal switching with change of the polarization modulus and (ii) transversal switching with virtual admixing of the a-component of polarization. The results are specified for the case of barium titanate oxide BaTiO3where the crossover line between two types of switching is found at strain-temperature phase diagram.
