Giant shifts of crystal-field excitations with temperature as consequence of internal magnetic exchange fields
Joel O'Brien, Guochu Deng, Dehong Yu +7
Crystal-field excitations, for example in transition-metal oxides where a rare-earth element is used as a spacer between the transition-metal-oxide tetrahedra and octahedra, are as…
Giant shifts of crystal-field excitations in ErFeO3 driven by internal magnetic fields
Joel O'Brien, Guochu Deng, Xiaoxuan Ma +6
Due to the complex interactions between rare-earth elements and transition metals, as well as/or themselves, rare-earth transition-metal oxides are likely to exhibit highly intrigu…
Jahn-Teller versus quantum effects in the spin-orbital material LuVO3
M. Skoulatos, S. Toth, B. Roessli +17
We report on combined neutron and resonant x-ray scattering results, identifying the nature of the spin-orbital ground state and magnetic excitations in LuVO3 as driven by the orbi…
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…
Field-driven magnetisation steps in Ca3Co2O6: A single-crystal neutron-diffraction study
C. L. Fleck, M. R. Lees, S. Agrestini +2
We present single-crystal neutron-diffraction data for the spin-chain compound Ca3Co2O6. The intensity and line shapes of the two families of Bragg peaks characterising both the an…
Spin gaps and magnetic structure of NaxCoO2
L. M. Helme, A. T. Boothroyd, R. Coldea +4
We present two experiments that provide information on spin anisotropy and the magnetic structure of NaxCoO2. First, we report low-energy neutron inelastic scattering measurements…
