Structural, Microstructural, and Magnetic Properties of Ce and Sr-<i>co</i>-Substituted (La_2-<i>x</i> Vac _<i>x</i> )NiTiO₆ (<i>x</i> = 0, 0.1) Perovskites.

ABSTRACT: The synthesis of materials in the La_2-x (CeSr) _m Sr _n □ _p NiTiO_6‑δ series (where □ denotes vacancies, with m, n, and p ranging from 0 to 0.2, and x = 2m + n + p taking values of 0.4 and 0.6) was attempted using a modified Pechini method. A comprehensive chemical, structural, and microstructural characterization was carried out using X-ray diffraction (conventional and synchrotron), neutron powder diffraction, selected area electron diffraction, high-resolution transmission electron microscopy, and X-ray absorption spectroscopy. The results highlight that single-phase samples are obtained for compositions with low cerium and low vacancy contents (m ≤ 0.1
