Measuring Magnetic Excitation Spectra Using Resonant Inelastic X-ray Scattering

Abstract

The advent of modern synchrotron radiation facilities providing extremely intense x-rays has enabled measuring momentum-resolved spin excitation spectra of magnetic materials, which have long been exclusively accessible through inelastic neutron scattering. In this article, we briefly review the recent development of hard x-ray resonant inelastic x-ray scattering (RIXS) and discuss few examples of RIXS measurements on iridium oxides.
