SPEctroMicroscopy image and O 1s NEXAFS on LRS and HRS region.
(a) The imaged PCMO surface by a micro-beam scan with incident energy of 529 eV. The pixel size is 1 μm × 1 μm. (b) The NEXAFS data of O 1s absorption at a spot in the dark region (HRS) and at a spot in the bright region (LRS). For reliable local area measurement, the range of energy was limited to 15 eV due to a depth of focus.
