Spin-state transition in the Fe-pnictides
H. Gretarsson, S. R. Saha, T. Drye +7
We report a Fe Kβx-ray emission spectroscopy study of local magnetic moments in the rare-earth doped iron pnictide Ca_{1-x}RE_xFe_2As_2 (RE=La, Pr, and Nd). In all samples studied…

Topological states in pyrochlore iridates: long-range anisotropy strongly competing with spin-orbit interaction
Liviu Hozoi, H. Gretarsson, J. P. Clancy +7
In the search for topological phases in correlated electron systems, iridium-based pyrochlores A2Ir2O7 -- materials with 5d transition-metal ions -- provide fertile grounds. Severa…

Crystal field splitting and correlation effect on the electronic structure of A2IrO3
H. Gretarsson, J. P. Clancy, X. Liu +16
The electronic structure of the honeycomb lattice iridates Na2IrO3 and Li2IrO3 has been investigated using resonant inelastic x-ray scattering (RIXS). Crystal-field split d-d excit…
