Impact of Mg substitution in LaMnO₃ manganites on their structural integrity and magnetic behavior.

ABSTRACT: In this study, we investigated the impact of Mg substitution at the La site in LaMnO₃ on its structural, chemical, and magnetic properties. To explore the effects of Mg doping, we synthesized a series of compositions, La_1-x Mg _x MnO₃ (x = 0.05, 0.1, 0.15, 0.2, 0.3, and 0.33), using a conventional solid-state method and systematically investigated their structural and magnetic properties. X-Ray diffraction patterns confirmed the formation of a pure rhombohedral crystal structure for the samples up to x = 0.15. However, for compositions with x > 0.15, the emergence of a secondary phase, MgMn₂O₄ with a spinel structure, was observed alongside the primary phase. Furthermore, it was observed tha
