Author(s): Jungho Kim, A. H. Said, D. Casa, M. H. Upton, T. Gog, M. Daghofer, G. Jackeli, J. van den Brink, G. Khaliullin, and B. J. Kim Using resonant inelastic x-ray scattering, we observe in the bilayer iridate Sr 3 Ir 2 O 7 , a spin-orbit coupling driven magnetic insulator with a small charge gap, a magnon gap of ≈92 meV for both acoustic and optical branches. This exceptionally large magnon gap exceeds the total magnon bandwidth of ≈... [Phys. Rev. Lett. 109, 157402] Published Wed Oct 10, 2012
