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…
Charge-Transfer Excitations in the Model Superconductor HgBaCuO
L. Lu, X. Zhao, G. Chabot-Couture +9
We report a Cu -edge resonant inelastic x-ray scattering (RIXS) study of charge-transfer excitations in the 2-8 eV range in the structurally simple compound HgBaCuO…
Structural and magnetic properties of the single-layer manganese oxide La{1-x}Sr{1+x}MnO4
S. Larochelle, A. Mehta, L. Lu +6
Using x-ray and neutron scattering, we have studied the structural and magnetic properties of the single-layer manganite La{1-x}Sr{1+x}MnO4 (0 < x < 0.7). Single crystals were grow…
Neutron Scattering, Magnetometry, and Quantum Monte Carlo Study of the Randomly-Diluted Spin-1/2 Square-Lattice Heisenberg Antiferromagnet
O. P. Vajk, M. Greven, P. K. Mang +1
We have successfully grown sizable single crystals of La_2Cu_{1-z}(Zn,Mg)_zO_4 with up to nearly half of the magnetic Cu sites replaced by non-magnetic Zn and Mg. Neutron scatterin…
