All-in all-out magnetic order and propagating spin-waves in Sm2Ir2O7

C. Donnerer, M. C. Rahn, M. Moretti Sala +7

Using resonant magnetic x-ray scattering we address the unresolved nature of the magnetic groundstate and the low-energy effective Hamiltonian of Sm${}_2$Ir${}_2$O${}_7$, a prototypical…
