Title: Giant Spin-Driven Ferroelectric Polarization in ${BiFeO}_{3}$ at Room Temperature

Abstract

Although BiFeO₃ is the most extensively investigated multiferroic material, its magnetoelectic couplings are barely understood. Here we report a thorough study of the magentoelectric (ME) couplings in spin-cycloidal buk BiFeO₃ using first-principles calculations and microscopic spin-wave models compared with neutron-scattering measurements. We find that huge exchange-striction (ES) polarizations, i.e. the electric response of the magnetic exchange through ferroelectric and antiferrodistortive distortions, is giant enough to dominate over all other ME couplings. We show that BiFeO₃ has a hidden record-high spin-driven polarization ( 3 C/cm²) at room-temperature. The huge ES polarizations can be tuned by coupling to the antiferrodistortive rotations.

First-principles approach to the dynamic magnetoelectric couplings for the non-reciprocal directional dichroism in BiFeO₃

Journal Article Kezsmarki, I. ; Fishman, Randy Scott - New Journal of Physics

Due to the complicated magnetic and crystallographic structures of BiFeO₃, its magnetoelectric (ME) couplings and microscopic model Hamiltonian remain poorly understood. By employing a firstprinciples approach, we uncover all possibleMEcouplings associated with the spin-current (SC) and exchange-striction (ES) polarizations, and construct an appropriate Hamiltonian for the long-range spin-cycloid in BiFeO₃. First-principles calculations are used to understand the microscopic origins of theMEcouplings.Wefind that inversion symmetries broken by ferroelectric and antiferroelectric distortions induce the SC and the ES polarizations, which cooperatively produce the dynamicME effects in BiFeO₃. A model motivated by first principles reproduces the absorption difference of counter-propagating light beams calledmore »« less

Weak exchange striction between the $4 f$ and $3 d$ ions in the multiferroic ${GdMn}_{2} O_{5}$

Journal Article Sheng, Jieming ; Tong, Xin Tony ; Ye, Feng ; ... - Physical Review B

We used single-crystal neutron diffraction to investigate the magnetic structures of the multiferroic GdMn₂O₅. The system undergoes a first-order incommensurate to commensurate magnetic transition below 33 K, accompanied by the appearance of electric polarization P. Upon cooling, P increases smoothly while the magnetic order shows an abrupt enhancement in intensity below 20 K owing to the large increase of the rare-earth Gd moment. The contrasting temperature evolution of the magnetic order and polarization indicates the polarization is mainly driven by the exchange striction between the magnetic Mn ions. The incommensurate phase in the intermediate temperature range has a cycloidal modulationmore »« less

Stabilization of Highly Polar ${BiFeO}_{3}$ -like Structure: A New Interface Design Route for Enhanced Ferroelectricity in Artificial Perovskite Superlattices

Journal Article Wang, Hongwei ; Wen, Jianguo ; Miller, Dean J. ; ... - Physical Review. X

In ABO₃ perovskites, oxygen octahedron rotations are common structural distortions that can promote large ferroelectricity in BiFeO₃ with an R3c structure [1] but suppress ferroelectricity in CaTiO₃ with a Pbnm symmetry [2]. For many CaTiO3-like perovskites, the BiFeO₃ structure is a metastable phase. Here, we report the stabilization of the highly polar BiFeO₃-like phase of CaTiO₃ in a BaTiO₃/CaTiO₃ superlattice grown on a SrTiO₃ substrate. The stabilization is realized by a reconstruction of oxygen octahedron rotations at the interface from the pattern of nonpolar bulk CaTiO₃ to a different pattern that is characteristic of a BiFeO₃ phase. The reconstruction ismore »« less

Successive field-induced transitions in ${BiFeO}_{3}$ around room temperature

Journal Article Kawachi, Shiro ; Miyake, Atsushi ; Ito, Toshimitsu ; ... - Physical Review Materials

The effects of high magnetic fields applied perpendicular to the spontaneous ferroelectric polarization on single crystals of BiFeO₃ were investigated in this paper through magnetization, magnetostriction, and neutron diffraction measurements. The magnetostriction measurements revealed lattice distortion of 2 x 10^-5 during the reorientation process of the cycloidal spin order by applied magnetic fields. Furthermore, anomalous changes in magnetostriction and electric polarization at a larger field demonstrate an intermediate phase between cycloidal and canted antiferromagnetic states, where a large magnetoelectric effect was observed. Neutron diffraction measurements clarified that incommensurate spin modulation along the [110]_hex direction in the cycloidal phase becomes Qmore »« less

Spin state and spectroscopic modes of multiferroic BiFeO $_{3}$

Journal Article Fishman, Randy Scott ; Haraldsen, Jason T. ; Furukawa, Nobuo ; ... - Physical Review. B, Condensed Matter and Materials Physics

Spectroscopic modes provide the most sensitive probe of the very weak interactions responsible for the properties of the long-wavelength cycloid in the multiferroic phase of BiFeO₃ below T_N ≈ 640 K. Three of the four modes measured by terahertz (THz) and Raman spectroscopies were recently identified using a simple microscopic model. While a Dzyaloshinskii-Moriya (DM) interaction D along [-1, 2, -1] induces a cycloid with wave vector (2π/α) (0.5 + δ, 0.5, 0.5 - δ) (δ ≈ 0.0045), easy-axis anisotropy K along the [1, 1, 1] direction of the electric polarization P induces higher harmonics of the cycloid, which split themore »« less
