Les ferrites spinelles sont des oxydes métalliques à structure spinelle dont la formule chimique générale est AB2O4. Grâce à leurs propriétés uniques et remarquables, les matériaux magnétiques, diélectrique des nanocristallins ont attiré l’attention de nombreux domaines, tels que la physique, la chimie, la biologie, la médecine, la science des matériaux et l’ingénierie. Dans ce travail de recherche, nous avons exploré deux axes de recherche principaux. Le premier concerne une étude approfondie sur les propriétés thermiques, structurales, électriques, thermodynamiques et diélectriques des composés spinelles synthétisées sous différentes températures de recuit pour diverses applications. L’objectif de cette étude est d’examiner comment la variation de la température de calcination modifie la microstructure, la taille des grains, et par conséquent, les propriétés fonctionnelles des ferrites, avec l’objectif de développer ces matériaux pour les applications d’hyper-fréquence et des micro-ondes. Le second axe de recherche se concentre sur l’importance des substitutions élémentaires du Co et Cr ions dans le système Li-Fe ferrite pour optimiser les propriétés physiques de ce composé.
