Description
We have analyzed the microstructure of LaMO3 perovskites (M=Ni,Co,Fe), which were synthesized by incipient wetness impregnation of mesoporous carbon spheres and subsequent sintering. In the case of LaNiO3, we identified Ruddlesden-Popper shear faults via transmission electron microscopy. We set up a structural model for these defects and fit it to complementary synchrotron and neutron data via Rietveld refinements. Local structure analysis supports the gained results.
