Field dependence of magnetic ordering in Kagome-staircase compound Ni3V2O8
(American Physical Society, 2006-07-01)
We present powder and single-crystal neutron diffraction and bulk measurements of the Kagome-staircase compound Ni3V2O8 (NVO) in fields up to 8.5 T applied along the c direction. (The Kagome plane is the a-c plane.) This ...
Magnetically driven ferroelectric order in Ni3V2O8
(American Physical Society, 2005-08-19)
We show that long-range ferroelectric and incommensurate magnetic order appear simultaneously in a single phase transition in Ni3V2O8. The temperature and magnetic-field dependence of the spontaneous polarization show a ...
