Title: Manifestation of ferroelectromagnetism in multiferroic BiMnO{sub 3}

Abstract

Multiferroic BiMnO{sub 3} with a highly distorted perovskite structure induced by the stereochemically active 6s{sup 2} electron lone pairs of Bi{sup 3+} was synthesized at a high pressure of 6 GPa. Magnetization, differential scanning calorimetry, dielectric permittivity, and in situ powder x-ray diffraction as a function of temperature were carried out, respectively. In light of comprehensive evaluation, we can conclude that the synthetic BiMnO{sub 3} ceramic displays ferromagnetic and ferroelectric orderings simultaneously, i.e., ferroelectromagnetism below its ferromagnetic Curie temperature T{sub M}{approx}100 K.

  • Resonant x-ray scattering is performed near the Mn K-absorption edge for an epitaxial thin film of BiMnO{sub 3}. The azimuthal angle dependence of the resonant (003) peak (in monoclinic indices) is measured with different photon polarizations; for the {sigma}{yields}{pi}{sup '} channel a threefold symmetric oscillation is observed in the intensity variation, while the {sigma}{yields}{sigma}{sup '} scattering intensity remains constant. These features are accounted for in terms of the peculiar ordering of the manganese 3d orbitals in BiMnO{sub 3}. It is demonstrated that the resonant peak persists up to 770 K with an anomaly around 440 K; these high and lowmore » temperatures coincide with the structural transition temperatures, seen in bulk, with and without a symmetry change, respectively. A possible relationship of the orbital order with the ferroelectricity of the system is presented.« less
  • The multiferroic material BiMnO{sub 3} synthesized under high pressure has been systematically studied by transmission electron microscopy and electron energy-loss spectroscopy, and some important structural defects are revealed in this multiferroic material. The frequently observed defects are characterized to be {sigma}3(111) twin boundaries, Ruddlesden-Popper [Acta Crystallogr. 11, 54 (1958)] antiphase boundaries, and a{sub p}<001>{sub p} superdislocations connected with a small segment of Ruddlesden-Popper defect. These defects are present initially in the as-synthesized sample. In addition, we find that ordered voids (oxygen vacancies) are easily introduced into the multiferroic BiMnO{sub 3} by electron-beam irradiation.
  • Although La{sup 3+} and Bi{sup 3+} ions have similar ionic radii, the Bi{sub 1-x}Sr{sub x}MnO{sub 3} system was found to show quite different behavior from La{sub 1-x}Sr{sub x}MnO{sub 3} in which ferromagnetism with metallic conductivity is achieved by the {open_quotes}double exchange mechanism.{close_quotes} BiMnO{sub 3} which was synthesized under high pressure is a ferromagnetic insulator with T{sub c} = 105 K, in contrast to antiferromagnetic insulator with T{sub c} = 105 K, in contrast to antiferromagnetic LaMnO{sub 3}. Though Sr substitution in BiMnO{sub 3} increased conductivity, no metallic state was achieved up to the solid solution limit of x = 0.67.more » Furthermore the saturation magnetic moment of 3.6 {mu}{sub B} observed in BiMnO{sub 3} decreased very rapidly with increasing x, and ferromagnetism disappeared for x>0.4. These observations suggest that the highly polarizable Bi{sup 3+} ion with 6s{sup 2} lone pair would cause local distortion of the perovskite lattice, which presumably reduces the mobility of carriers. The origin of ferromagnetism in BiMnO{sub 3} requires a mechanism other than the double exchange theory.« less
  • Crystal structures of solid solutions of BiMn{sub 1-x}Sc{sub x}O{sub 3} with x=0.05, 0.1, 0.2, 0.3, 0.4, 0.5, and 0.7 were studied with synchrotron X-ray powder diffraction. The strong Jahn-Teller distortion, observed in BiMnO{sub 3} at 300 K and associated with orbital order, disappeared already in BiMn{sub 0.95}Sc{sub 0.05}O{sub 3}. The orbital-ordered phase did not appear in BiMn{sub 0.95}Sc{sub 0.05}O{sub 3} down to 90 K. Almost the same octahedral distortions were observed in BiMn{sub 1-x}Sc{sub x}O{sub 3} with 0.05<=x<=0.7 at room temperature and in BiMnO{sub 3} at 550 K above the orbital ordering temperature T{sub OO}=473 K. These results allowed usmore » to conclude that the remaining octahedral distortions observed in BiMnO{sub 3} above T{sub OO} are the structural feature originated from the highly distorted monoclinic structure. - Graphical Abstract: Compositional dependence of octahedral distortion parameters DELTA(M1O{sub 6}) and DELTA(M2O{sub 6}) in solid solutions BiMn{sub 1-x}Sc{sub x}O{sub 3} at 300 K.« less
  • Growth of multifunctional thin films on flexible substrates is of great technological significance since such a platform is needed for flexible electronics. In this study, we report the growth of biaxially aligned (BiFeO{sub 3}){sub 0.5}:(BiMnO{sub 3}){sub 0.5} [BFO-BMO] films on polycrystalline Hastelloy by using a biaxially aligned TiN as a seed layer deposited by ion-beam-assisted deposited and a La{sub 0.7}Sr{sub 0.3}MnO{sub 3} (LSMO) as a buffer layer deposited by pulsed laser deposition. The LSMO is used not only as a buffer layer but also as the bottom electrode of the BFO-BMO films. X-ray diffraction showed that the BFO-BMO films aremore » biaxially oriented along both in-plane and out-of-plane directions. The BFO-BMO films on flexible metal substrates showed a polarization of 22.9 μC/cm{sup 2}. The magnetization of the BFO-BMO/LSMO is 62 emu/cc at room temperature.« less
