“…LaFe 0.5 Cr 0.5 O 3 was synthesized using the sol-gel method [12,13], with all reagents being analytically pure. Following the stoichiometric ratio, La(NO 3 ) 3 •6H 2 O, Fe(NO 3 ) 3 •9H 2 O, and Cr(NO 3 ) 3 •9H 2 O were dissolved in deionized water, followed by the addition of an excess amount of ethylene glycol and citric acid, which maintained a stoichiometric ratio of 3:1 with the metal nitrates, and magnetic stirring was conducted at 100℃ with a magnetic stirrer.…”

LaFe0.5Cr0.5O3 was prepared by sol-gel method, and the obtained samples were annealed at 750°C and 900°C. The magnetic hysteresis curves illustrated that the coercivity of the samples increased with higher annealing temperatures. Magnetic tests revealed anomalous behavior in the M-T curve of LFCO-900 within the temperature range of 50K-150K, which can be attributed to changes in magnetic entropy induced by annealing. The annealing temperature has a significant impact on the magnetic properties of LFCO. Monte Carlo simulation was employed to simulate the dependence of the magnetization on the temperature in disordered systems under weak and strong fields, and the results were consistent with the phenomena of LFCO-750. These findings provide important reference values for in-depth studies to understand the physical properties of perovskite materials, and they contribute to the optimization of the magnetic entropy effect in perovskite systems, thus enhancing their application value.

“…The linear extrapolation of the energy plot allowed the determination of the Eg values, which were found to be equal to 2.57, 2.50, and 1.22 eV for Cr, Ti, and Mn-doped samples, respectively. Consequently, these materials are candidates for photovoltaic devices and single junction solar cell [48]. The decrease in the band gap energy value observed for the Mn-doped compound can be explained by the difference in the ionic radii, which decreases the octahedral rotation, leading to a reduction in the band gap.…”

In the present work, the morphological, optical, and gas-sensing properties of La0.67Ca0.2Ba0.13Fe0.97M0.03O3 (M = Ti, Cr, and Mn) nano-powders prepared via the auto-combustion route, were investigated. TEM images prove the nanoscale particle size of all the samples. Optical studies confirm the semiconductor behavior of the studied materials. The response of the prepared nano-powders towards the presence of two gas-reducing agents (ethanol and acetone) was investigated. From the resistance ratio under air and gas, it was possible to determine the response to different gases and deduce that La0.67Ca0.2Ba0.13Fe0.97Ti0.03O3 presents the highest responses to ethanol and acetone. Likewise, we deduced that the prepared materials were able to detect low concentrations of ethanol and acetone gases.
