This study presents a comprehensive investigation of the structural and magnetic properties of LaSrMnCoO (LS1, LS2 and LS3) compounds synthesized the sol-gel method at different gelation temperatures through X-ray diffraction and different magnetic measurement techniques. The Rietveld refinement demonstrated that all samples exhibit a rhombohedral perovskite structure with the 3̄ space group. Their magnetic behavior, characterized through magnetization measurements, hysteresis loops, and Arrot plots, demonstrates a ferromagnetic-paramagnetic transition with notable soft ferromagnetic characteristics.

The present work proposes the best realistic theoretical approaches to examine the experimental conductivity data taken for LaCaMnNbO. For this purpose, we comprehensively discussed the structural, microstructural, and electrical properties of the LaCaMnNbO perovskite. Both X-ray diffraction and Rietveld analysis show the orthorhombic structure of the ceramic.

This article presents the annealing effect on the structural, elastic, thermodynamic, optical, magnetic, and electric properties of NiZnFeAlO (NZFAO) nanoparticles (NPs). The samples were successfully synthesized by the sol-gel method followed by annealing of the as-synthesized at 600, 800, 900, 1050, and 1200 °C. This approach yielded the formation of a highly crystalline structure with crystallite size ranging from 17 nm to 40 nm.

Magnetoimpedance spectroscopy was carried out on phase-separated LaCaMnO polycrystalline manganites. The LaCaMnO powder was synthesized following an adapted sol-gel route. Structural and magnetic data showed the signs of phase coexistence of ferromagnetic (FM) Pnma and charge-ordered antiferromagnetic (CO-AFM) P2/m phases.
