The samples were prepared with a concentration step of 1–5 mol %. The isothermal cross-sections of the La<sub>2</sub>O<sub>3</sub>–Fe<sub>2</sub>O<sub>3</sub> phase diagram at 1300 °C are characterized by the presence of three single-phase (A–La<sub>2</sub>O<sub>3</sub>, LaFeO<sub>3</sub>, Fe<sub>2</sub>O<sub>3</sub>), two two-phase (A–La<sub>2</sub>O<sub>3</sub>+LaFeO<sub>3</sub>, LaFeO<sub>3</sub>+Fe<sub>2</sub>O<sub>3</sub>) regions. The composition corresponding to the perovskite phase is 49 mol % La<sub>2</sub>O<sub>3</sub>–51 mol % Fe<sub>2</sub>O<sub>3</sub>. Nanocomposites based on the perovskite phase (LaFeO<sub>3</sub>) were obtained by the Pechini method and heterogeneous precipitation from nitrate solutions. Solutions of La<sup>3+</sup> nitrates, which were obtained by dissolving lanthanum oxide with a content of the main component of 99.99 % in nitric acid. The influence of the production method on the microstructure, morphology, and magnetic properties of nanopowders (LaFeO<sub>3</sub>) was studied. According to XRD, infrared spectroscopy, SEM, and TEM, the synthesized perovskite LaFeO<sub>3</sub> is single-phase with a particle size of 50–60 nm. The morphology of powder particles primarily depends on the method of material synthesis. The powder showed ferrimagnetic magnetic properties and had a specific magnetization 0.2 and 0.15 emu/g.</p></div>","PeriodicalId":432,"journal":{"name":"Solid State Sciences","volume":"157 ","pages":"Article 107699"},"PeriodicalIF":3.4,"publicationDate":"2024-09-13","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"142243264","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":3,"RegionCategory":"化学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
