Magnetic Superstructure and Metal-Insulator Transition in Mn-Substituted Sr3Ru2O7
M. A. Hossain, B. Bohnenbuck, Y. -D. Chuang +18
We present a temperature-dependent resonant elastic soft x-ray scattering (REXS) study of the metal-insulator transition in Sr3(Ru1-xMnx)2O7, performed at both Ru and Mn L-edges. R…
Magnetic structure of RuSrGdCuO determined by resonant x-ray diffraction
B. Bohnenbuck, I. Zegkinoglou, J. Strempfer +11
X-ray diffraction with photon energies near the Ru L-absorption edge was used to detect resonant reflections characteristic of a G-type superstructure in RuSrGdCuO…
Magnetic field induced transitions in multiferroic TbMnO3 probed by resonant and non-resonant X-ray diffraction
J. Strempfer, B. Bohnenbuck, I. Zegkinoglou +4
Multiferroic TbMnO3 is investigated using x-ray diffraction in high magnetic fields. Measurements on first and second harmonic structural reflections due to modulations induced by…
Spin-charge-lattice coupling near the metal-insulator transition in Ca3Ru2O7
C. S. Nelson, H. Mo, B. Bohnenbuck +4
We report x-ray scattering studies of the c-axis lattice parameter in Ca3Ru2O7 as a function of temperature and magnetic field. These structural studies complement published transp…
Absence of commensurate ordering at the polarization flop transition in multiferroic DyMnO3
J. Strempfer, B. Bohnenbuck, M. Mostovoy +6
Ferroelectric spiral magnets DyMnO3 and TbMnO3 show similar behavior of electric polarization in applied magnetic fields. Studies of the field dependence of lattice modulations on…
Incommensurate structure of the spin-Peierls compound TiOCl
A. Krimmel, J. Strempfer, B. Bohnenbuck +8
We report on a detailed single crystal x-ray diffraction study of the unconventional spin-Peierls compound TiOCl. The intermediate phase of TiOCl is characterized by an incommensur…
