Magnetic nanoparticles (NPs) are attractive both for their fundamental properties and for their potential in a variety of applications ranging from nanomedicine and biology to micro/nanoelectronics and catalysis. While these fields are dominated by the use of iron oxides, reduced metal NPs are of interest since they display high magnetization and adjustable anisotropy according to their size, shape and composition. The use of organometallic precursors makes it possible to adjust the size, shape (sphere, cube, rod, wire, urchin, …) and composition (alloys, core-shell, composition gradient, dumbbell, …) of the resulting NPs and hence their magnetic properties. We discuss here the synthesis of magnetic metal NPs from organometallic precursors carried out in Toulouse, as well as their associated properties and their potential in applications.
