Antiferromagnetic spin canting and Magnetoelectric Multipoles in h-YMnO
M. Ramakrishnan, Y. Joly, Q. N. Meier +7
Hexagonal YMnO is a prototype antiferromagnet which exhibits multiferroic behavior with the ferroelectric and magnetic transitions occurring at different temperatures. We obs…
Crystal Symmetry Lowering in Chiral Multiferroic BaTaFeSiO observed by X-Ray Magnetic Scattering
M. Ramakrishnan, Y. Joly, Y. W. Windsor +8
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-r…
X-ray Magnetic and Natural Circular Dichroism from first principles: Calculation of K- and L1-edge spectra
N. Bouldi, N. J. Vollmers, C. G. Delpy-Laplanche +8
An efficient first principles approach to calculate X-ray magnetic circular dichroism (XMCD) and X-ray natural circular dichroism (XNCD) is developed and applied in the near edge r…
Resonant X-ray diffraction studies on the charge ordering in magnetite
E. Nazarenko, J. E. Lorenzo, Y. Joly +3
Here we show that the low temperature phase of magnetite is associated with an effective, although fractional, ordering of the charge. Evidence and a quantitative evaluation of the…
A critical reexamination of the non-reciprocal x-ray gyrotropy in VO
S. Di Matteo, Y. Joly, C. R. Natoli
We critically review the experimental determination of the nonreciprocal x-ray gyrotropy in the monoclinic antiferromagnetic insulating phase of VO highlighting some of its…
