Magnetic nanoparticle properties and microstructure formation in liquid dispersions

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.
