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…
Spin wave measurements over the full Brillouin zone of multiferroic BiFeO3
Jaehong Jeong, E. A. Goremychkin, T. Guidi +9
Using inelastic neutron scattering technique, we measured the spin wave dispersion over the entire Brillouin zone of room temperature multiferroic BiFeO3 single crystals with magne…
Analysis of magnetization and a spin state crossover in the multiferroic CaCoMnO
R. Flint, H. -T. Yi, P. Chandra +2
Ca_3Co_{2-x}Mn_xO_6 (x ~ 0.96) is a multiferroic with spin-chains of alternating Co(2+) and Mn(4+) ions. The spin state of Co(2+) remains unresolved, due to a discrepancy between h…
Nanoscale anisotropic structural correlations in the paramagnetic and ferromagnetic phases of Nd0.5Sr0.5 MnO3
V. Kiryukhin, B. G. Kim, T. Katsufuji +2
We report x-ray scattering studies of short-range structural correlations and diffuse scattering in Nd0.5Sr0.5MnO3. On cooling, this material undergoes a series of transitions, fir…
Magnetic properties of the S=1/2 quasi-one-dimensional antiferromagnet CaCu2O3
V. Kiryukhin, Y. J. Kim, K. J. Thomas +5
We report single crystal growth and magnetic susceptibility and neutron diffraction studies of the S=1/2 quasi-1D antiferromagnet CaCu2O3. The structure of this material is similar…
Reentrant Spin-Peierls Transition in Mg-Doped CuGeO_3
V. Kiryukhin, Y. J. Wang, S. C. LaMarra +4
We report a synchrotron x-ray scattering study of the diluted spin-Peierls (SP) material Cu_{1-x}Mg_xGeO_3. In a recent paper we have shown that the SP dimerization attains long-ra…
