Phase relations in the Nd2O3-Fe2O3 system: Structure and magnetic properties of perovskite NdFeO3 ceramics 2024 Access copy available to the general public Unrestricted The phase relations in the Nd2O3-Fe2O3 system at 1300 and 1400 degrees C were studied in the whole concentration range by X-ray diffraction (XRD) and scanning electron microscopy (SEM). The isothermal cross-sections of the Nd2O3-Fe2O3 phase diagram at 1300 and 1400 degrees C are characterized by the presence of three single-phase (A-Nd2O3, NdFeO3, Fe2O3) and two two-phase (A-Nd2O3 + NdFeO3, NdFeO3 + Fe2O3) regions. The composition corresponding to the perovskite phase is 51 mol% Nd2O3 - 49 mol% Fe2O3. In the next step, the investigation was focused on this composition. Nanocrystalline NdFeO3 powders with perovskite structure were obtained by the Pechini method and heterogeneous precipitation from nitrate solutions. The influence of the production method on the microstructure, morphology and magnetic properties of the NdFeO3 nanopowders was studied. According to XRD, SEM and TEM, the synthesized perovskite NdFeO3 is single-phase with a particle size of 60-90 nm. The morphology of powder particles primarily depends on the synthesis method. The powder showed ferromagnetic behaviour and had saturation magnetization 0.8 and 0.81 emu/g. info:eu-repo/grantAgreement/EC/H2020/872631 /EU/Memristive and multiferroic materials for emergent logic units in nanoelectronics/MELON This project has received funding from the European Union’s Horizon 2020 research and innovation program under grant agreement No H2020 872631 -MELON info:eu-repo/semantics/openAccess by https://creativecommons.org/licenses/by/4.0/deed.es 0.8 2024 MATERIALS SCIENCE, CERAMICS 26 / 34 = 0.765 2024 Q4 T3 0.239 2024 Ceramics and Composites 2024 Q3 1.6 2024 info:eu-repo/semantics/article info:eu-repo/semantics/publishedVersion Vedel, Dmytro V.
