Figure 5
Spectral resolution function and magnon spectrum in Sr₃Ir₂O₇. (a) The measured resolution function of the quartz (309) diced spherical analyzer (blue filled circles) and a fitted resolution function (green line), FWHM of 10.53 $[\pm]$ 0.1 meV. (b) Magnon spectrum in Sr₃Ir₂O₇ at momentum transfer Q = (1, 0, 26.5) measured with with quartz analyzer (10.53 meV: black line, left axis) and Si (844) analyzer (30 meV: red line, right axis). The peak at the zero energy loss is the elastic scattering and the magnon peak at ∼90 meV.
