Title: Commensurate Dy magnetic ordering associated with incommensurate lattice distortion in multiferroic DyMnO{sub 3}

Abstract

Synchrotron x-ray diffraction and resonant magnetic scattering experiments on a single crystal of orthorhombic DyMnO{sub 3} have been carried out between 4 and 40 K. Below T{sub N}{sup Dy}=5 K, the Dy magnetic moments order in a commensurate structure with propagation vector 0.5 b{sup *}. Simultaneous with the Dy magnetic ordering, an incommensurate lattice modulation with propagation vector 0.905 b{sup *} evolves while the original Mn induced modulation is suppressed and shifts from 0.78 b{sup *} to 0.81 b{sup *}. This points to a strong interference of Mn and Dy induced structural distortions in DyMnO{sub 3} besides a magnetic coupling between the Mn and Dy magnetic moments.

  • Element specific x-ray resonant magnetic scattering (XRMS) investigations were undertaken to determine the magnetic structure of the multiferroic compound, hexagonal DyMnO{sub 3}. In the temperature range from 68 K down to 8 K the Dy{sup 3+} moments are aligned and antiferromagnetically correlated in the c direction according to the magnetic representation {Gamma}{sub 3}. The temperature dependence of the observed intensity can be modeled assuming the splitting of ground-state doublet crystal-field levels of Dy{sup 3+} by the exchange field of Mn{sup 3+}. XRMS together with magnetization measurements indicate that the magnetic representation is {Gamma}{sub 2} below 8 K.
  • Neutron powder diffraction and single crystal x-ray resonant magnetic scattering measurements suggest that Dy plays an active role in enhancing the ferroelectric polarization in multiferroic DyMnO{sub 3} above T{sub N}{sup Dy}=6.5 K. We observe the evolution of an incommensurate ordering of Dy moments with the same periodicity as the Mn spiral ordering. It closely tracks the evolution of the ferroelectric polarization. Below T{sub N}{sup Dy}, where Dy spins order commensurately, the polarization decreases to values similar for those of TbMnO{sub 3}. The higher P{sub s} found just above T{sub N}{sup Dy} arises from the contribution of Dy spins so asmore » to effectively increase the amplitude of the Mn spin spiral.« less
  • This paper investigates the magnetic properties of Ho{sub 1-x}Dy{sub x}MnO{sub 3} by considering the inter-planar Mn{sup 3+}-O-O-Mn{sup 3+} interaction. The theoretical analysis shows that the asymmetric in-plane exchange interaction couples the in-plane and inter-planar Mn{sup 3+} spin structures via asymmetry parameter δ. This leads to the existence of both the in-plane and inter-planar ordering, which in turn restricted the allowed magnetic space groups to Γ{sub 1} and Γ{sub 4}. The experimental studies confirmed the concomitant nature of the in-plane and the inter-planar ordering at T{sub N}, T{sub SR}, and T{sub 2}. It also showed that the magnetic phase diagram ismore » dominated by the allowed magnetic structures Γ{sub 1} and Γ{sub 4}. Furthermore, an effort is made to resolve the inconsistency regarding the T{sub SR} (32 or 40 K). The studies revealed that the antiferromagnetic inter-planar interaction is switched to the ferromagnetic interaction (40 K) upon cooling, which in turn drives the spin reorientation at 32 K. The Mn{sup 3+} spin structure is seen to be coupled to rare earth sub-lattice through the modulation of the inter-planar interaction.« less
  • The authors report a new structure determination of the Sr{sub 1.2872}NiO{sub 3} incommensurate composite hexagonal perovskite compound. Three different refinement strategies are presented: (1) a 3D supercell approximation with a nonharmonic development of the atomic displacement factor, (2) an original (3+1)D incommensurate composite description with the use of crenel functions, and (3) a (3+1)D commensurate composite model. The three strategies are discussed and compared to previous refinements carried out for the hexagonal perovskites in a classical way or with the superspace group formalism. Out of the three methods, the incommensurate composite approach gives slightly better results with a final globalmore » R value of 2.89% for 635 independent reflections and only 60 parameters (R{bar 3}m(00{gamma})Os) superspace group. The use of crenel functions notably improves previously reported results. New structural features are evidenced for Sr{sub 1.2872}NiO{sub 3}: (1) an incommensurate character, (2) a splitting of the trigonal prismatic nickel atoms over 5 positions, (3) a definite stoichiometry which induces a perfect charge balance, and (4) a nonharmonic behavior of some Sr atoms. Those characteristics seem general to most hexagonal perovskite compounds and essential for correctly interpreting their interesting magnetic properties. Finally, a new generic formulation is proposed, which explains the various stoichiometries observed and suggests a new compound possibility.« less
  • Here, we present the first example of magnetic ordering-induced multiferroic behavior in a metal–organic framework magnet. This compound is [CH 3NH 3][Co(HCOO) 3] with a perovskite-like structure. The A-site [CH 3NH 3] + cation strongly distorts the framework, allowing anisotropic magnetic and electric behavior and coupling between them to occur. This material is a spin canted antiferromagnet below 15.9 K with a weak ferromagnetic component attributable to Dzyaloshinskii–Moriya (DM) interactions and experiences a discontinuous hysteretic magnetic-field-induced switching along [010] and a more continuous hysteresis along [101]. Coupling between the magnetic and electric order is resolved when the field is appliedmore » along this [101]: a spin rearrangement occurs at a critical magnetic field in the ac plane that induces a change in the electric polarization along [101] and [10-1]. The electric polarization exhibits an unusual memory effect, as it remembers the direction of the previous two magnetic-field pulses applied. The data are consistent with an inverse-DM mechanism for multiferroic behavior.« less
