Magnetic phases in the Kagome staircase compound Co3V2O8
N. R. Wilson, O. A. Petrenko, L. C. Chapon
The low temperature properties of the Kagome-type system Co3V2O8 have been studied by powder neutron diffraction both in zero field and in applied magnetic field of up to 8 T. Belo…
Structural phase transition and magnetism in hexagonal srmno
A. Daoud-Aladine, C. Martin, L. C. Chapon +4
The structural and magnetic properties of the hexagonal four-layer form of SrMnO have been investigated by combining magnetization measurements, electron diffraction and high-r…
Symmetry constraints on the electrical polarization in novel multiferroic materials
P. G. Radaelli, L. C. Chapon
The symmetry conditions for the development of a macroscopic electrical polarization as a secondary order parameter to a magnetic ordering transition, and the constraints on the di…
Enhanced ferroelectric polarization by induced Dy spin-order in multiferroic DyMnO3
O. Prokhnenko, R. Feyerherm, E. Dudzik +4
Neutron powder diffraction and single crystal x-ray resonant magnetic scattering measurements suggest that Dy plays an active role in enhancing the ferroelectric polarization in mu…
Non-collinear long-range magnetic ordering in HgCr2S4
L. C. Chapon, P. G. Radaelli, Y. S. Hor +2
The low-temperature magnetic structure of \HG has been studied by high-resolution powder neutron diffraction. Long-range incommensurate magnetic order sets in at T22K with…
