The incommensurate magnetic structure of YMn2O5: a stringent test of the multiferroic mechanism
P. G. Radaelli, C. Vecchini, L. C. Chapon +3
We have determined the magnetic structure of the low-temperature incommensurate phase of multiferroic YMn2O5 using single-crystal neutron diffraction. By employing corepresentation…
A Neutron diffraction study of multiferroics RMn2O5
P. G. Radaelli, L. C. Chapon
The magnetic properties of RMn2O5 multiferrroics as obtained by unpolarized and polarized neutron diffraction experiments are reviewed. We discuss the qualitative features of the m…
Electric field switching of antiferromagnetic domains in YMn2O5: a probe of the multiferroic mechanism
P. G. Radaelli, L. C. Chapon, A. Daoud-Aladine +5
We employ neutron spherical polarimetry to determine the nature and population of the coexisting antiferromagnetic domains in multiferroic YMn2O5. By applying an electric field, we…
Competing magnetic interactions in the extended Kagome system YBaCo4O7
L. C. Chapon, P. G. Radaelli, H. Zheng +1
YBaCo4O7 belongs to a new class of geometrically frustrated magnets like the pyrochlores, in which Co-spins occupy corners of tetrahedra. The structure can be viewed as an alternat…
Ferroelectricity induced by acentric spin-density waves in YMnO
L. C. Chapon, P. G. Radaelli, G. R. Blake +2
The commensurate and incommensurate magnetic structures of the magnetoelectric system YMnO, as determined from neutron diffraction, were found to be spin-density waves…
