Exchange interactions, Jahn-Teller coupling, and multipole orders in pseudospin one-half $5 d^{2}$ Mott insulators

Giniyat Khaliullin, Derek Churchill, P. Peter Stavropoulos +1

We develop a microscopic theory of multipole interactions and orderings in 5 $d^{2}$ transition metal ion compounds. In a cubic environment, the ground state of 5 $d^{2}$ ions is a non-K…

Optical magnons with dominant bond-directional exchange interactions in a honeycomb lattice iridate $α$ -Li $_{2}$ IrO $_{3}$

Sae Hwan Chun, P. Peter Stavropoulos, Hae-Young Kee +6

We have used resonant inelastic x-ray scattering to reveal optical magnons in a honeycomb lattice iridate $α$ -Li $_{2}$ IrO $_{3}$ . The spectrum in the energy region 20-25 meV exhibit…
