Spin reorientation in the square-lattice antiferromagnets RMnAsO (R = Ce, Nd): Density functional analysis of the spin exchange interactions between the rare-earth and transition-metal ions
Changhoon Lee, Erjun Kan, Hongjun Xiang +4
The spin reorientation (SR) phenomenon of the square-lattice antiferromagnets RMnAsO (R = Ce, Nd) was investigated by analyzing the spin exchange interactions between the rare-eart…
CuBr2-A New Multiferroic Material with High Critical Temperature
L. Zhao, T. L. Hung, C. C. Li +10
A new multiferroic material, CuBr2, is reported for the first time. CuBr2 has not only a high transition temperature (close to liquid nitrogen temperature) but also low dielectric…
On the nature of the spin frustration in the CuO2 ribbon chains of LiCuVO4: Crystal structure determination at 1.6 K, magnetic susceptibility analysis and density functional evaluation of the spin exchange constants
Hyun-Joo Koo, Changhoon Lee, Myung-Hwan Whangbo +2
The spin-1/2 Cu2+ ions of LiCuVO4 form one-dimensional chains along the b-direction, and the spin frustration in LiCuVO4 is described in terms of the nearest-neighbor ferromagnetic…
Single-ion anisotropy, Dzyaloshinskii-Moriya interaction and negative magnetoresistance of the spin-1/2 pyrochlores R2V2O7
H. J. Xiang, E. J. Kan, M. -H. Whangbo +3
The electronic and magnetic properties of spin-1/2 pyrochlores R2V2O7 were investigated on the basis of density-functional calculations. Contrary to the common belief, the spin-1/2…
Ferromagnetically coupled Shastry-Sutherland quantum spin singlets in (CuCl)LaNbO
C. Tassel, J. Kang, C. Lee +10
Using inelastic neutron scattering, x-ray, neutron diffraction, and the first-principle calculation techniques, we show that the crystal structure of the two-dimensional quantum sp…
Density functional analysis of the simultaneous charge/spin order and the associated Cu-Fe intersite charge transfer in LaCu3Fe4O12
Changhoon Lee, Erjun Kan, Myung-Hwan Whangbo
LaCu3Fe4O12 undergoes a phase transition at 393 K involving the spin order (SO) of the Fe sites and the charge order (CO) resulting in Cu-Fe intersite charge transfer. On the basis…
