Electronic phase transitions in quantum 3d materials at high pressure by RIXS : the case of SrFeO2 and BaFe2Se3

Résumé

Pressure is an effective mean to alter the structural, electronic and magnetic response of 3d quantum materials as the change of the atomic distances affect the electron density, orbital hybridization and crystal electric field strength. RIXS appears as a powerful tool of characterization of materials under high pressure [1]. Here we will illustrate this approach through recent RIXS high pressure studies realized at GALAXIES beamline, SOLEIL synchrotron. We will address more specifically the stability of the spin state in the square planar Fe compound SrFeO2 [2] and the interplay with superconductivity in the BaFe2Se3 spin ladder compounds [3]. Perspectives for high pressure RIXS studies at GALAXIES beamline in line with the Upgrade of SOLEIL Synchrotron will be discussed.
