Abstract It is generally believed that epitaxial thin films are subject to compressive strain by the nearest layer with a smaller lattice constant or to tensile strain by the nearest layer with aExpand
100-nm-sized magnetic domain reversal by the magneto-electric effect in self-assembled BiFeO3/CoFe2O4 bilayer films
The results suggest that self-assembled BiFeO3/CoFe2O4 bilayers are interesting in voltage driven nonvolatile memory with a low manufacturing cost. Expand
Multiferroic BaTiO3–BiFeO3 composite thin films and multilayers: strain engineering and magnetoelectric coupling
BiFeO3 and BaTiO3 were used to grow homogeneous composite thin films and multilayer heterostructures with 15 double layers by pulsed laser deposition. The perpendicular strain of the films was tunedExpand

Epitaxial self-assembly of multiferroic nanostructures
The morphology and structure of interfaces in PbTiO3–CoFe2O4 films on SrTiO3 substrates of various orientations are studied. It is found that for film with thickness more than 100 nm with columnarExpand
On the strain coupling across vertical interfaces of switchable BiFeO3–CoFe2O4 multiferroic nanostructures
In magnetoelectrically coupled CoFe2O4–BiFeO3 nanostructures vertical and lateral lattice parameters of both phases are determined. We find that the in-plane lattice parameter of CoFe2O4 is fullyExpand
Phenomenological theory of 1–3 type multiferroic composite thin film: thickness effect
The effect of thickness on the para–ferro-phase transition temperatures, the spontaneous polarization and magnetization and hysteresis loops of 1–3 type multiferroic composite thin films was studiedExpand
Strain control and spontaneous phase ordering in vertical nanocomposite heteroepitaxial thin films.
Major advances on all fronts are demonstrated: remarkable spontaneously ordered structures were produced in newly predicted compositions, vertical strain was proven to dominate the strain state in films above 20 nm thickness and strain manipulation was demonstrated by selection of phases with the appropriate elastic moduli.

Effect of substrate-induced strains on the spontaneous polarization of epitaxial BiFeO3 thin films
A single-domain thermodynamic theory is employed to predict the spontaneous polarizations of (001)c, (101)c, and (111)c oriented epitaxial BiFeO3 thin films grown on dissimilar substrates. TheExpand
Controlling self-assembled perovskite-spinel nanostructures.
It is reported a discovery that self-assembled perovskite-spinel nanostructures can be controlled simply by selecting single-crystal substrates with different orientations, attributed to the surface energy anisotropy as an intrinsic property of a crystal. Expand
Structure and interface chemistry of perovskite-spinel nanocomposite thin films
The structure and the interface chemistry of epitaxial BiFeO3–NiFe2O4 nanocomposite thin films on SrTiO3(001) substrates were investigated using the Z-contrast imaging and the electron exit-waveExpand
Electric field-induced magnetization switching in epitaxial columnar nanostructures.
We present direct evidence for room-temperature magnetization reversal induced by an electric field in epitaxial ferroelectric BiFeO3-ferrimagnetic CoFe2O4 columnar nanostructures. PiezoelectricExpand
Multiferroic BaTiO3-CoFe2O4 Nanostructures
Thermodynamic analyses show that the magnetoelectric coupling in a nanostructured BaTiO3-CoFe2O4 ferroelectromagnet can be understood on the basis of the strong elastic interactions between the two phases. Expand
