Polarization vortex domains induced by switching electric field in ferroelectric films with circular electrodes
Laurent Baudry, Anaïs Sené, Igor A. Luk'yanchuk +2
We describe ferroelectric thin films with circular electrodes and develop a thermodynamic theory that explains previously mysterious experiments. It is found to be especially usefu…
Field-induced vortices in weakly anisotropic ferroelectrics
Anais Sene, Laurent Baudry, Igor A. Luk'yanchuk +1
In the micro- and nanoscale ferroelectric samples, the formation and the growth of domains are the usual stages of the polarization switching mechanism. By assuming the weak polari…
Stability of Vortex Phases in Ferroelectric Easy-Plane nano-Cylinders
L. Lahoche, I. Luk'yanchuk, G. Pascoli
Bounded charges induced by the polarization gradient in finite-size ferroelectrics are known to produce the unfavorable depolarization electric field that suppresses the uniform fe…
Universal Properties of Ferroelectric Domains
Igor A. Lukyanchuk, Laurent Lahoche, Anais Sene
Basing on Ginzburg-Landau approach we generalize the Kittel theory and derive the interpolation formula for the temperature evolution of a multi-domain polarization profile P(x,z).…
