Spherical neutron polarimetry with Cryopad-II

Noncentrosymmetric commensurate magnetic ordering of multiferroic ErMn2O5

“…Moreover we demonstrate that for a structure containing several magnetic sublattices and few symmetry constraints, it is only by combining precise single crystal neutron diffraction intensity measurements with quantitative spherical neutron polarimetry [15] on the same specimens that different possible magnetic configurations may be clearly distinguished.…”

Crystallography Under Extreme Conditions: State of the Art and Perspectives

“…Hot polarized neutron diffraction is also a very interesting technique used to obtain crucial information about the magnetic form factors (reflecting the state of the magnetic ions) and magnetisation distributions of para-, ferro-and some antiferro-magnetic single-crystal materials if measurements are performed under high magnetic field configuration. On the other hand, one can performed zero-field neutron polarimetry measurements using Cryopad (CRYOgenic Polarization Analysis Device) (Tasset et al, 1999;Lelièvre-Berna et al, 2005;Takeda et al, 2005) to refine complex antiferromagnetic structures or to perform accurate determination of antiferromagnetic distributions.…”
