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…
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…
Origin of the large polarization in multiferroic YMnO thin films revealed by soft and hard x-ray diffraction
H. Wadati, J. Okamoto, M. Garganourakis +9
We investigated the magnetic structure of an orthorhombic YMnO3 thin film by resonant soft x-ray and hard x-ray diffraction. We observed a temperature-dependent incommensurate magn…
Circularly polarized resonant soft x-ray diffraction study of helical magnetism in hexaferrite
A M Mulders, S M Lawrence, A J Princep +7
Magnetic spiral structures can exhibit ferroelectric moments as recently demonstrated in various multiferroic materials. In such cases the helicity of the magnetic spiral is direct…
