“…Previously this method was successfully utilized for the synthesis of high-quality single [31,32] and mixed-metal oxide materials [33][34][35] with magnetic and electrical properties. Different bi-and tri-metallic manganites with magnetic properties were also prepared by sol-gel combustion using glycine-nitrate method [36][37][38]. However, in all these reports starting materials were dissolved in a certain amount of solvent, which leads to more time-consuming synthetic procedure.…”

In this study, the Bi x La 1−x MnO 3+δ solid solutions (x 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 3+ content. Scanning electron microscopy (SEM) was used to evaluate morphological features of the synthesized materials and revealed that Bi 3+ ions significantly promote growth of the grains. The sol-gel-derived Bi x La 1−x MnO 3+δ 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.

“…The CaMnO 3 system remarkably exhibited separation on the FC and ZFC branches, where the data revealed a sharp increase at a particular temperature. This change may be associated with the twocomponent magnetic antiferromagnetic and ferromagnetic-like ordering [22]. Figure 3d shows the temperature dependence of dχ/dT according to the ZFC curve.…”

This paper describes the CaTi 1−x Mn x O 3 (x = 0.0, 0.4, 0.6, 0.8 and 1.0) system synthesis using the solid-state reaction (SSR) method. The structural, morphological, and magnetic properties of Mn ion were evaluated in the CaTiO 3 system through X-ray diffraction patterns (XRD), scanning electron microscopy + electron-dispersive spectroscopy (SEM + EDS), and vibrating sample magnetometry. Rietveld analysis of the XRDs at room temperature evidenced that the samples crystallized in the Pnma (62) space group. Likewise, the XRDs showed that lattice parameters decreased when increasing Mn content. The SEM + EDS results exhibited typical features of samples obtained by SSR at high temperatures. The zero-field cooling and field cooling curves of magnetization in temperatures ranging from 50 to 300 K showed paramagnetic behavior in the applied field for each Mn-doped sample with a possible weak ferromagnetic-like ordering. Conversely, the CaMnO 3 sample exhibited antiferromagnetic ordering with T N near 113.26 K.
