A ferroelectric crystal exhibits a stable and switchable electrical polarization that is manifested in the form of cooperative atomic displacements. A ferromagnetic crystal exhibits a stable and switchable magnetization that arises through the quantum mechanical phenomenon of exchange. There are very few ‘multiferroic’ materials that exhibit both of these properties, but the ‘magnetoelectric’ coupling of magnetic and electrical properties is a more general and widespread phenomenon. Although… 
The magnetoelectric domains and cross-field switching in multiferroic BiFeO3
BiFeO3 is an exciting multiferroic material because of its room temperature multiferrocity, excellent ferroelectric properties, and recently demonstrated electric control of antiferromagnetic
Multiferroic Materials: Physics and Properties
Multiferroics are materials in which magnetism and ferroelectricity coexist. They are of fundamental interest to understand electronic behavior coupling magnetic interactions and electric dipolar
Magnetoelectric complex-oxide heterostructures
A short review of recent progress in the field of multiferroic thin films and heterostructures is given. We focus on the bismuth iron oxide system due to its desirable properties, namely high
Multiferroics: a magnetic twist for ferroelectricity.
TLDR
It is found that even a weak magnetoelectric interaction can lead to spectacular cross-coupling effects when it induces electric polarization in a magnetically ordered state.
Electrically controlled magnetization switching in a multiferroic heterostructure
A demonstration of magnetization reversal via the application of electric field across a multiferroic heterostructure, consisting of a FeCoV ribbon bonded to a lead magnesium niobate-lead titanate
Polarization and magnetization dynamics of a field-driven multiferroic structure.
TLDR
It is demonstrated that for material parameters corresponding to BaTiO(3)/Fe the polarization and the magnetization are controllable by external magnetic and electric fields, respectively.

TLDR
Emphasis is placed on how a subset of such interfaces, namely ferromagnet–ferroelectric heterostructures, display electronically mediated control of magnetism and, in particular, on how these effects manifest themselves as detectable spin-dependent transport phenomena.
Controlling magnetism with multiferroics
Multiferroics, materials combining multiple order parameters, offer an exciting way of coupling phenomena such as electronic and magnetic order. Using epitaxial growth and heteroepitaxy, researchers
Persistent multiferroicity without magnetoelectric effects in CuO
Multiferroicity and magnetoelectric effects in CuO have been investigated by measurements of magnetization, dielectric constant, and electric polarization with and without magnetic fields. Dielectric
Antiferromagnetic and Ferroelectric Phase Transitions and Instabilities in PFW-PT Multiferroic Solid Solution Characterized by Anelastic Measurement
Magnetic, electric and mechanical behaviors are strongly coupled, but only a few models are able to describe electro-magneto-mechanical coupling effects. In this work, multiferroic solid solutions

Magnetocapacitance effect in multiferroic BiMnO 3
We have investigated the structural, magnetic, and electric properties of ferromagnetic BiMnO 3 with a highly distorted perovskite structure. At T E = 750-770 K, a
Electric polarization reversal and memory in a multiferroic material induced by magnetic fields
TLDR
A striking interplay between ferroelectricity and magnetism in the multiferroic TbMn2O5 is reported, demonstrated by a highly reproducible electric polarization reversal and permanent polarization imprint that are both actuated by an applied magnetic field.
Why Are There so Few Magnetic Ferroelectrics
Multiferroic magnetoelectrics are materials that are both ferromagnetic and ferroelectric in the same phase. As a result, they have a spontaneous magnetization that can be switched by an applied
Multi-ferroic magnetoelectrics
Abstract Domain aspects of multi-ferroics are reviewed, i.e. of materials, in which two or all three of the properties ‘ferroelectricity.’ ‘ferromagnetism’ and ‘ferroelasticity’ occur simultaneously
Magnetocapacitance without magnetoelectric coupling
The existence of a magnetodielectric (magnetocapacitance) effect is often used as a test for multiferroic behavior in new material systems. However, strong magnetodielectric effects can also be

TLDR
It is shown that biasing the ferroelectric YMnO3 layer by an electric field allows control of the magnetic exchange bias and subsequently the magnetotransport properties of the FM layer, which may contribute to paving the way towards a new generation of electric-field controlled spintronic devices.
