Figure 12
SEM images of the Nd0.9 sample after reduction in wet H₂ at 650 °C. The image on the right is a detail (green box) of the image on the left at a higher magnification. Exsolved nanoparticles are visible at the perovskite surface, with diameters of around 200 nm. An EDX mapping was performed of the magnified area. The Fe distribution, characterized by the net intensity of the Fe L peak, is shown as an overlay. The particles visible in the secondary electron image coincided with a higher Fe concentration.
