Special Issue "Multiferroics"
Deadline for manuscript submissions: closed (30 November 2010)
In recent years, multiferroics has received significant attention in the field of material science. Multiferroics is a material that possesses two- or three- of ferroic properties: ferroelectricity, ferromagnetism, and ferroelasticity. The current trend is to focus on ferroelectric-ferromagnetism. Due to the interaction between the electric polarization and magnetic polarization, coexistence of ferroelectricity and ferromagnetism has the possibility to exhibit the magneto-electric effects, e.g., electric polarization is changed by an external magnetic field, or, magnetic polarization is changed by an external electric field. From the viewpoint of optical properties, a ferroelectric material has nonlinear optical activity, and, hence, a ferroelectric-ferromagnet will show a nonlinear magneto-optical effect such as magnetization-induced second harmonic generation. Magneto-electric effects on multiferroic are expected to produce the future devises. Based on these potentials, the discovery of multiferroic materials is one of the targets in the field of material science, chemistry, and physics. This special issue invites contributions from the fields where novel multiferroic materials contributed to the area of advanced material synthesis, and novel magneto-electric effects contributed to the area of advanced physics and functionalities.
