An x-ray diffraction study of the temperature-induced structural phase transitions in SmVO3
R. D. Johnson, C. C. Tang, I. R. Evans +7
Through powder x-ray diffraction we have investigated the structural behavior of SmVO3, in which orbital and magnetic degrees of freedom are believed to be closely coupled to the c…
Competing Ferri- and Antiferromagnetic Phases in Geometrically Frustrated LuFe2O4
J. de Groot, K. Marty, M. D. Lumsden +12
We present a detailed study of magnetism in LuFe2O4, combining magnetization measurements with neutron and soft x-ray diffraction. The magnetic phase diagram in the vicinity of T_N…
Magnetically induced electric polarization reversal in multiferroic TbMnO: Terbium spin reorientation studied by resonant x-ray diffraction
R. D. Johnson, C. Mazzoli, S. R. Bland +2
In multiferroic TbMnO, the behavior of the terbium ions forms a crucial part of the magneto-electric coupling. The result is a magnetically induced reversal of the electric…
Antiferromagnetically spin polarized oxygen observed in magneto-electric TbMn2O5
T. A. W. Beale, S. B. Wilkins, R. D. Johnson +8
We report the direct measurement of antiferromagnetic spin polarization at the oxygen sites in the multiferroic TbMn2O5, through resonant soft x-ray magnetic scattering. This suppo…
Nature of the magnetic order and origin of induced ferroelectricity in TbMnO
S. B. Wilkins, T. R. Forrest, T. A. W. Beale +9
The magnetic structures which endow TbMnO with its multiferroic properties have been reassessed on the basis of a comprehensive soft x-ray resonant scattering (XRS) study. The…
Determination of magnetic order of the rare-earth ions in multiferroic TbMn2O5
R. D. Johnson, S. R. Bland, C. Mazzoli +5
We have employed resonant x-ray magnetic scattering to specifically probe the magnetic order of the rare-earth ions in multiferroic . Two energy resonances were…
