Intensity of well-screened structure of Mn 2p spectra, free energy profiles, and charge and orbital arrangements. Upper panel: integrated intensity of the well-screened structure of Mn 2p core-level spectra of Pr0.55(Ca1 − ySry)0.45MnO3 (y = 0.25) as a function of temperature. The integrated intensity represents the volume fraction of the FM state, and those in the cooling and warming processes are indicated by the close triangles and open circles, respectively. The integrated intensities after laser illumination are indicated by closed diamonds and closed squares. The arrows denote the changes caused by the laser illumination. Lower panel: conceptual drawings for the charge and orbital arrangements for the FM state with the ferromagnetic orbital polarons and for the COOI state.
