Crystal symmetry lowering in chiral multiferroic Ba 3 TaFe 3 Si 2 O 14 observed by x-ray magnetic scattering
Physical Review B, 2017Co-Authors: M. Ramakrishnan, Yves Joly, Y. W. Windsor, L. Rettig, A. Alberca, E. M. Bothschafter, P. Lejay, R. Ballou, V. Simonet, V. ScagnoliAbstract:Chiral multiferroic langasites have attracted attention due to their doubly chiral magnetic ground state within an Enantiomorphic Crystal. We report on a detailed resonant soft x-ray diffraction study of the multiferroic Ba3TaFe3Si2O14 at the FeL2,3 and oxygenK edges. BelowTN (≈27K)we observe the satellite reflections (0,0,τ ), (0,0,2τ ), (0,0,3τ ), and (0,0,1 − 3τ) where τ ≈ 0.140 ± 0.001. The dependence of the scattering intensity on x-ray polarization and azimuthal angle indicate that the odd harmonics are dominated by the out-of-plane (ˆc axis) magnetic dipole while the (0,0,2τ ) originates from the electron density distortions accompanying magnetic order.We observe dissimilar energy dependencies of the diffraction intensity of the purelymagnetic odd-harmonic satellites at the Fe L3 edge. Utilizing first-principles calculations, we show that this is a consequence of the loss of threefold Crystal symmetry in the multiferroic phase.

ScagnoliAbstract:Chiral multiferroic langasites have attracted attention due to their doubly chiral magnetic ground state within an Enantiomorphic Crystal. We report on a detailed resonant soft x-ray diffraction study of the multiferroic ${\mathrm{Ba}}_{3}{\mathrm{TaFe}}_{3}{\mathrm{Si}}_{2}{\mathrm{O}}_{14}$ at the Fe ${L}_{2,3}$ and oxygen $K$ edges. Below ${T}_{N}$ ($\ensuremath{\approx}27K$) we observe the satellite reflections $(0,0,\ensuremath{\tau}), (0,0,2\ensuremath{\tau}), (0,0,3\ensuremath{\tau})$, and $(0,0,1\ensuremath{-}3\ensuremath{\tau})$ where $\ensuremath{\tau}\ensuremath{\approx}0.140\ifmmode\pm\else\textpm\fi{}0.001$. The dependence of the scattering intensity on x-ray polarization and azimuthal angle indicate that the odd harmonics are dominated by the out-of-plane ($\stackrel{\ifmmode \hat{}\else \^{}\fi{}}{\mathbf{c}}$ axis) magnetic dipole while the $(0,0,2\ensuremath{\tau})$ originates from the electron density distortions accompanying magnetic order.
