Epitaxial growth and magnetoelectric relaxor behavior in multiferroic 0.8Pb(Fe1/2Nb1/2)O3-0.2Pb(Mg1/2W1/2)O3 thin films
Wei Peng, N. Lemée, J. -L. Dellis +8
We present electric and magnetic properties of 0.8Pb(Fe1/2Nb1/2)O3-0.2Pb(Mg1/2W1/2)O3 films epitaxially grown on (001) SrTiO3 substrates using pulsed laser deposition. A narrow dep…
Origin of Ferroelastic Domains in Free-Standing Single Crystal Ferroelectric Films
I. A. Luk'yanchuk, A. Schilling, J. M. Gregg +2
The origin of the unusual 90^o ferroelectric / ferroelastic domains, consistently observed in recent studies on meso and nanoscale free-standing single crystals of BaTiO3 [Schillin…
Spin-lattice coupling in multiferroic Pb(Fe1/2Nb1/2)O3 thin films
W. Peng, N. Lemée, M. Karkut +7
We have made magnetization and x-ray diffraction measurements on an epitaxial Pb(Fe1/2Nb1/2)O3 200 nm film. From the temperature dependence of the out-of-plane lattice parameter we…
Epitaxial growth and structural characterization of Pb(Fe1/2Nb1/2)O3 thin films
W. Peng, N. Lemée, J Holc +3
We have grown lead iron niobate thin films with composition Pb(Fe1/2Nb1/2)O3 (PFN) on (0 0 1) SrTiO3 substrates by pulsed laser deposition. The influence of the deposition conditio…
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).…
