{ "description": "<p>In this study, the Bi<sub>x</sub>La<sub>1−x</sub>MnO<sub>3+δ</sub> solid solutions (<em>x</em> from 0 to 0.65) were synthesized using sol–gel combustion method with citric acid as a fuel and complexing agent. It was shown that changes in chemical composition of the materials lead to the evolution of crystal structure, morphology, and magnetic properties. The thermal behavior of precursor gel was investigated by thermogravimetric and differential scanning calorimetry (TG-DSC) measurements. X-ray diffraction (XRD) analysis demonstrated that all samples were monophasic. The Rietveld analysis showed that the structure can be indexed by trigonal or cubic unit cell depending on Bi<sup>3+</sup> content. Scanning electron microscopy (SEM) was used to evaluate morphological features of the synthesized materials and revealed that Bi<sup>3+</sup> ions significantly promote growth of the grains. The sol–gel-derived Bi<sub>x</sub>La<sub>1−x</sub>MnO<sub>3+δ</sub> specimens were also characterized by FT-IR spectroscopy and magnetization measurements, which showed a clear correlation between magnetic properties and crystal structure of the materials.</p>", "license": "https://creativecommons.org/licenses/by/4.0/legalcode", "creator": [ { "affiliation": "Institute of Chemistry, Vilnius University, Naugarduko 24, LT-03225, Vilnius, Lithuania", "@type": "Person", "name": "Dovydas Karoblis" }, { "affiliation": "State Research Institute Center for Physical Sciences and Technology, LT-02300, Vilnius, Lithuania", "@type": "Person", "name": "Kestutis Mazeika" }, { "affiliation": "State Research Institute Center for Physical Sciences and Technology, LT-02300, Vilnius, Lithuania", "@type": "Person", "name": "Dalis Baltrunas" }, { "affiliation": "Institute of Low Temperature and Structure Research, Polish Academy of Sciences, Okolna 2, PL-50422, Wroclaw, Poland", "@type": "Person", "name": "Anna Lukowiak" }, { "affiliation": "Institute of Low Temperature and Structure Research, Polish Academy of Sciences, Okolna 2, PL-50422, Wroclaw, Poland", "@type": "Person", "name": "Wieslaw Strek" }, { "affiliation": "Institute of Chemistry, Vilnius University, Naugarduko 24, LT-03225, Vilnius, Lithuania", "@type": "Person", "name": "Aleksej Zarkov" }, { "affiliation": "Institute of Chemistry, Vilnius University, Naugarduko 24, LT-03225, Vilnius, Lithuania", "@type": "Person", "name": "Aivaras Kareiva" } ], "headline": "Novel synthetic approach to the preparation of single-phase BixLa1\u2212xMnO3+\u03b4 solid solutions", "image": "https://zenodo.org/static/img/logos/zenodo-gradient-round.svg", "datePublished": "2019-08-03", "url": "https://zenodo.org/record/4290683", "keywords": [ "Bismuth manganite", "Sol-gel processing", "Paramagnetic" ], "@context": "https://schema.org/", "identifier": "https://doi.org/10.1007/s10971-019-05098-w", "@id": "https://doi.org/10.1007/s10971-019-05098-w", "@type": "ScholarlyArticle", "name": "Novel synthetic approach to the preparation of single-phase BixLa1\u2212xMnO3+\u03b4 solid solutions" }
