The structural, electronic and magnetic properties of Fe7S8 material have been studied within the framework of the ab-initio calculations, the mean field approximation (MFA) and Monte Carlo simulation (MCS). Our study shows that two forms of the iron

Synthesis of La0.5Ca0.5-x xMnO3 nanocrystalline manganites by sucrose assisted auto combustion route and study of their structural, magnetic and magnetocaloric properties

Autor: Moumen, S. Ben, Gagou, Y., Chettab, M., Mezzane, D., Amjoud, M., Fourcade, S., Hajji, L., Kutnjak, Z., Marssi, M. El, Amraoui, Y. El, Kopelevich, Y., Lukyanchuk, Igor A.

Perovskite manganite La0.5Ca0.5-x xMnO3 (LCMO) nanomaterials were elaborated using the sucrose modified auto combustion method. Rietveld refinements of the X-ray diffraction patterns of the crystalline structure confirm a single-phase orthorhombic st
