Unconventional magnetic order on the hyperhoneycomb Kitaev lattice in -Li2IrO3: full solution via magnetic resonant x-ray diffraction
A. Biffin, R. D. Johnson, Sungkyun Choi +6
The recently-synthesized iridate -LiIrO has been proposed as a candidate to display novel magnetic behavior stabilized by frustration effects from bond-dependent, anisot…
Dimerization-Induced Cross-Layer Quasi-Two-Dimensionality in Metallic Iridate IrTe2
G. L. Pascut, K. Haule, M. J. Gutmann +7
The crystal structure of layered metal IrTe2 is determined using single-crystal x-ray diffraction. At T=220 K, it exhibits Ir and Te dimers forming a valence-bond crystal. Electron…
X-ray imaging and multiferroic coupling of cycloidal magnetic domains in ferroelectric monodomain BiFeO3
R. D. Johnson, P. Barone, A. Bombardi +6
Magnetic domains at the surface of a ferroelectric monodomain BiFeO3 single crystal have been imaged by hard X-ray magnetic scattering. Magnetic domains up to several hundred micro…
Slow Magnetic Order-Order Transition in the Spin Chain Antiferromagnet Ca3Co2O6
S. Agrestini, C. L. Fleck, L. C. Chapon +4
Using powder neutron diffraction we have discovered an unusual magnetic order-order transition in the Ising spin chain compound Ca3Co2O6. On lowering the temperature an antiferroma…
Direct observation of charge order in triangular metallic AgNiO2 by single-crystal resonant X-ray scattering
G. L. Pascut, R. Coldea, P. G. Radaelli +5
We report resonant X-ray scattering measurements on the orbitally-degenerate triangular metallic antiferromagnet 2H-AgNiO2 to probe the spontaneous transition to a triple-cell supe…
Helical spin-waves, magnetic order, and fluctuations in the langasite compound Ba3NbFe3Si2O14
C. Stock, L. C. Chapon, A. Schneidewind +6
We have investigated the spin fluctuations in the langasite compound Ba3NbFe3Si2O14 in both the ordered state and as a function of temperature. The low temperature magnetic structu…
