Melting of chiral order in terbium manganate (TbMnO3) observed with resonant x-ray Bragg diffraction
S W Lovesey, V Scagnoli, M Garganourakis +3
Resonant Bragg diffraction of soft, circularly polarized x-rays has been used to observe directly the temperature dependence of chiral-order melting in a motif of Mn ions in terbiu…
Dzyaloshinsky-Moriya driven helical-butterfly structure in Ba3NbFe3Si2O14
V. Scagnoli, S. W. Huang, M. Garganourakis +5
We have used soft x-ray magnetic diffraction at the Fe3+ L2,3 edges to examine to what extent the Dzyaloshinsky-Moriya interaction in Ba3NbFe3Si2O14 influences its low temperature…
Identification of coherent lattice modulations coupled to charge and orbital order in a manganite
A. Caviezel, S. O. Mariager, S. L. Johnson +7
We apply grazing-incidence femtosecond x-ray diffraction to investigate the details of the atomic motion connected with a displacively excited coherent optical phonon. We concentra…
Phase competitions in epitaxial PrCaMnO/LaSrMnO superlattices
H. Wadati, J. Okamoto, M. Garganourakis +5
We studied the charge-orbital ordering in the superlattice of charge-ordered insulating PrCaMnO and ferromagnetic metallic LaSrMnO by resona…
Imprinting magnetic information in manganites with X-rays
M. Garganourakis, V. Scagnoli, S. W. Huang +6
The effect of x-rays on an orbital and charge ordered epitaxial film of a PrCaMnO is presented. As the film is exposed to x-rays, the antiferromagnetic respon…
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…
