Magnetic inversion symmetry breaking and ferroelectricity in TbMnO3
M. Kenzelmann, A. B. Harris, S. Jonas +7
TbMnO3 is an orthorhombic insulator where incommensurate spin order for temperature T_N < 41K is accompanied by ferroelectric order for T < 28K. To understand this, we establish th…

Magnetic Order and Spin Dynamics in Ferroelectric HoMnO
O. P. Vajk, M. Kenzelmann, J. W. Lynn +2
Hexagonal HoMnO is a frustrated antiferromagnet (T=72 K) ferroelectric (T=875 K) in which these two order parameters are coupled. Our neutron measurements of the…
