Giant improper ferroelectricity in the ferroaxial magnet CaMn7O12
R. D. Johnson, L. C. Chapon, D. D. Khalyavin +3
In rhombohedral CaMn7O12, an improper ferroelectric polarization of magnitude 2870 μC m-2 is induced by an incommensurate helical magnetic structure that evolves below TN1 = 90 K.…
Cu3Nb2O8: a multiferroic with chiral coupling to the crystal structure
R. D. Johnson, Sunil Nair, L. C. Chapon +5
By combining bulk properties, neutron diffraction and non-resonant X-ray diffraction measurements, we demonstrate that the new multiferroic CuNbO becomes polar simultan…
Helical scattering signatures of strain and electronic textures in YbFe2O4 from three-dimensional reciprocal space imaging
Alexander J. Hearmon, Dharmalingam Prabhakaran, Harriott Nowell +3
The insulating ternary oxide YbFeO displays an unusual frustration-driven incommensurate charge-ordering (CO) transition, linked to possible ferroelectricity. Based on high…
