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

Abstract

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 modulation along the c axis, with spin configuration projected in the ab plane similar to the commensurate phase. The lack of observable bulk polarization suggests the exchange striction is not the dominant mechanism for the polarization in the incommensurate phase.

Complex magnetic order in the decorated spin-chain system ${Rb}_{2} {Mn}_{3} {({MoO}_{4})}_{3} {(OH)}_{2}$

Journal Article Liu, Yaohua ; Sanjeewa, Liurukara D. ; Garlea, V. Ovidiu ; ... - Physical Review B

The macroscopic magnetic properties and microscopic magnetic structure of Rb₂Mn₃(MoO₄)₃ (OH)₂ (space group Pn ma) are investigated by magnetization, heat capacity, and single-crystal neutron diffraction measurements. The compound's crystal structure contains bond-alternating [Mn₃ O₁₁] ^∞ chains along the b axis, formed by isosceles triangles of Mn ions occupying two crystallographically nonequivalent sites (the Mn1 site on the base and Mn2 site on the vertex). These chains are only weakly linked to each other by nonmagnetic oxyanions. Both superconducting quantum interference device magnetometry and neutron diffraction experiments show two successive magnetic transitions as a function of temperature.

Neutron scattering studies of the ferroelectric distortion and spin dynamics in the type-1 multiferroic perovskite ${Sr}_{0.56} {Ba}_{0.44} {MnO}_{3}$

Journal Article Pratt, Daniel K. ; Lynn, Jeffrey W. ; Mais, James ; ... - Physical Review. B, Condensed Matter and Materials Physics

The magnetic order, spin dynamics, and crystal structure of the multiferroic Sr0.56Ba0.44MnO3 have been investigated using neutron and x-ray scattering. Ferroelectricity develops at T-C = 305 K with a polarization of 4.2 mu C/cm(2) associated with the displacements of the Mn ions, while the Mn4+ spins order below T-N approximate to 200 K into a simple G-type commensurate magnetic structure. Below TN the ferroelectric order decreases dramatically, demonstrating that the two order parameters are strongly coupled. The ground state spin dynamics is characterized by a spin gap of 4.6(5) meV and the magnon density of states peaking at 43 meV.more »« less

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

Journal Article Lee, Jun Hee ; Fishman, Randy S. - Physical Review Letters

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.

Soft antiphase tilt of oxygen octahedra in the hybrid improper multiferroic ${Ca}_{3} {Mn}_{1.9} {Ti}_{0.1} O_{7}$

Journal Article Ye, Feng ; Wang, Jinchen ; Sheng, Jieming ; ... - Physical Review B

Here, we report a single crystal neutron and x-ray diffraction study of the hybrid improper multiferroic Ca₃Mn_1.9Ti_0.1O₇ (CMTO), a prototypical system where the electric polarization arises from the condensation of two lattice distortion modes. With increasing temperature (T), the out-of-plane, antiphase tilt of MnO₆ decreases in amplitude while the in-plane, in-phase rotation remains robust and experiences abrupt changes across the first-order structural transition. Application of hydrostatic pressure (P) to CMTO at room temperature shows a similar effect. The consistent behavior under both T and P reveals the softness of antiphase tilt and highlights the role of the partially occupied dmore »« less

Magnetic field induced antiferromagnetic cone structure in multiferroic ${BiFeO}_{3}$

Journal Article Matsuda, Masaaki ; Dissanayake, Sachith E. ; Hong, Tao ; ... - Physical Review Materials

Neutron diffraction measurements were performed under high magnetic fields up to 17 T in a multiferroic BiFeO₃ single crystal, in which an intermediate magnetic (IM) phase has been found between the cycloid and canted antiferromagnetic phases [S. Kawachi et al., Phys. Rev. Mater. 1, 024408 (2017)]. We clearly found that the incommensurate magnetic peaks, which split perpendicular to the magnetic field in the cycloid phase, rotate by 90 deg to align parallel to the field in the IM phase. The magnetic structure in the IM phase can be best described by an antiferromagnetic cone (AF cone) structure. The transition frommore »« less
