Dynamical magnetoelectric effects in multiferroic oxides.
Multiferroics with coexistent ferroelectric and magnetic orders can provide an interesting laboratory to test unprecedented magnetoelectric (ME) responses and their possible applications. One such example is the dynamical and/or resonant coupling between magnetic and electric dipoles in a solid. As examples of such dynamical ME effects, (i) the multiferroic domain wall dynamics and (ii) the ele...
متن کاملMagnetoelectric coupling in the multiferroic compound LiCu2O2
We investigate the possible types of coupling between ferroelectricity and magnetism for the zigzag spin chain multiferroic compound LiCu2O2. We construct a multi-order-parameter phenomenological model for the material based on a group theoretical analysis. We find that a theory involving interchain magnetoelectric coupling belonging to the same unit cell explains the experimental results of Pa...
متن کاملSynthetic magnetoelectric coupling in a nanocomposite multiferroic
Given the paucity of single phase multiferroic materials (with large ferromagnetic moment), composite systems seem an attractive solution to realize magnetoelectric coupling between ferromagnetic and ferroelectric order parameters. Despite having antiferromagnetic order, BiFeO3 (BFO) has nevertheless been a key material due to excellent ferroelectric properties at room temperature. We studied a...
متن کاملRoom-temperature magnetoelectric coupling in single-phase BaTiO3-BiFeO3 system
In this paper, single-phase multiferroic ceramics of (1 x) BaTiO3 x BiFeO3 (BT x BFO) were synthesized by solid-solution method in the wide range of material composition (x1⁄4 0.025 – 1.0). The changes in crystal structure were confirmed via X-ray diffractions (XRD) and atomic pair distribution functions (PDFs). The room-temperature ME coupling was found to exhibit significant magnitude in the ...
متن کاملCorrelation of High Magnetoelectric Coupling with Oxygen Vacancy Superstructure in Epitaxial Multiferroic BaTiO3-BiFeO3 Composite Thin Films
Epitaxial multiferroic BaTiO₃-BiFeO₃ composite thin films exhibit a correlation between the magnetoelectric (ME) voltage coefficient αME and the oxygen partial pressure during growth. The ME coefficient αME reaches high values up to 43 V/(cm·Oe) at 300 K and at 0.25 mbar oxygen growth pressure. The temperature dependence of αME of the composite films is opposite that of recently-reported BaTiO₃...
