Advances in high-resolution RIXS for the study of excitation spectra under high pressure
Hard x-ray resonant inelastic x-ray scattering (RIXS) is a promising x-ray spectroscopic tool for measuring low-energy excitation spectra at high pressure which have been stymied heretofore by the technical difficulties inherent in measuring a sample held at high pressure in a diamond anvil cell. The currently available facilities of high resolution (< 200 meV) RIXS has been used to probe low-energy excitation spectra from the diamond anvil cell, by virtue of advanced photon detection instrumentations of high-brilliance synchrotron x-ray radiation sources. Compared to a structural elastic scattering and x-ray emission, RIXS is a photon hungry technique and high-resolution RIXS under high pressure is at its infancy stage. In this review, the fundamentals of RIXS including instrumentation of high-resolution RIXS are presented and then experimental details of diamond anvil cell, sample preparation and measurement geometry are discussed. Experimental data of 3d and 5d transition metal oxides are presented. Finally, future improvements in high-resolution RIXS instrumentation for the high pressure experiment is discussed.
