Epitaxial BiFeO3 Multiferroic Thin Film Heterostructures
Enhanced polarization and related properties in heteroepitaxially constrained thin films of the ferroelectromagnet, BiFeO3, and combined functional responses in thin film form present an opportunity to create and implement thin film devices that actively couple the magnetic and ferroelectric order parameters.
The origin of ferroelectricity in magnetoelectric YMnO3
This work identifies the nature of the ferroelectric phase transition in the hexagonal manganite, YMnO3, using a combination of single-crystal X-ray diffraction, thorough structure analysis and first-principles density-functional calculations, and suggests an avenue for designing novel magnetic ferroelectrics.

Multiferroics: progress and prospects in thin films.
Novel device paradigms based on magnetoelectric coupling are discussed, the key scientific challenges in the field are outlined, and high-quality thin-film multiferroics are reviewed.
Weak ferromagnetism and magnetoelectric coupling in bismuth ferrite
We analyze the coupling between the ferroelectric and magnetic order parameters in the magnetoelectric multiferroic $\mathrm{Bi}\mathrm{Fe}{\mathrm{O}}_{3}$ using density functional theory within the
Advances in magnetoelectric multiferroics
Progress in the fundamental understanding and design of new multiferroic materials, advances in characterization and modelling tools to describe them, and usage in applications are reviewed.
Conduction at domain walls in oxide multiferroics.
The observation of room-temperature electronic conductivity at ferroelectric domain walls in the insulating multiferroic BiFeO(3) shows that the conductivity correlates with structurally driven changes in both the electrostatic potential and the local electronic structure, which shows a decrease in the bandgap at the domain wall.

The Renaissance of Magnetoelectric Multiferroics
Magnetoelectric multiferroics combine ferromagnetism (a spontaneous magnetization that can be switched by a magnetic field) and ferroelectricity (a spontaneous electric polarization that can be
Landau theory of topological defects in multiferroic hexagonal manganites.
It is shown that structural vortices induce magnetic ones and that, consistent with a recent experimental report, ferroelectric domain walls can carry a magnetic moment.
