Time-Resolved Hard X-Ray RIXS on Sr₂IrO₄ at SACLA

Abstract

　We aimed to demonstrate Floquet engineering of magnetic interactions in Sr₂IrO₄ using time-resolved RIXS (Resonant Inelastic X-ray Scattering). The experiment faced challenges, including low x-ray flux, air scattering, and limited detector efficiency, which reduced data quality. Despite this, we confirmed spectrometer alignment and identified improvements for future runs, including optimized beam path and enhanced detector sensitivity, ensuring robust measurements at SACLA.
