Abstract :
The physical properties and microstructures of magnetite and cobalt ferrite nanoparticles, dispersed in liquid matrices, are studied. Qualitative and quantitative analyses of static magnetization curves were performed. Magneto-granulometric results were obtained and interactions and agglomerations were evidenced, as a function of the preparation techniques as well as carrier liquids and surfactants used
