Non-Ising Character of a Ferroelectric Wall Arises from a Flexoelectric Effect
Yijia Gu, Menglei Li, Anna N. Morozovska +4
Using the classic ferroelectric BaTiO as an example, we show that the 180 degree ferroelectric domain wall, long considered to be of Ising-type and charge neural, contains both…
Novel multiferroics with ferromagnetic phase induced in paraelectric antiferromagnets by electric field application
Maya D. Glinchuk, Eugene A. Eliseev, Yijia Gu +3
The phase diagram of a quantum paraelectric antiferromagnet EuTiO3 under an external electric field was calculated using Landau-Ginzburg-Devonshire theory. It was shown that the ap…
Low-symmetry monoclinic phase stabilized by oxygen octahedra rotations in thin strained EuxSr1-xTiO3 films
Anna N. Morozovska, Yijia Gu, Victoria V. Khist +4
Using Landau-Ginzburg-Devonshire theory and phase field modeling, we explore the complex interplay between the long-range structural order parameter (oxygen octahedron rotations) a…
Universal emergence of spatially-modulated structures induced by flexo-antiferrodistortive coupling in multiferroics
Eugene A. Eliseev, Sergei V. Kalinin, Yijia Gu +6
We proved the existence of a universal flexo-antiferrodistortive coupling as a necessary complement to the well-known flexoelectric coupling. The coupling is universal for all anti…
