Research Abstract

I demonstrated in this research that magnetic excitations in 5d transition metal oxides, focusing on iridium oxides here, can be observed by resonant inelastic scattering using synchrotron radiation x-rays. I introduced new optical devices and achieved the best energy resolution of 70 meV. Using the high-energy resolution, I successfully observed dispersive magnetic excitations in Sr_2_IrO_4 and Sr_3Ir_2O_7 and their temperature dependence, which clarified the effect of two-dimensional magnetic interaction in the materials.
