We present the synthesis, structural and magnetic characterization of cobalt-based nanocrystals with controlled size (5–25 nm; 71 nm) and tailored morphologies (spheres, discs with specific aspect ratio of 5 20 nm and core-shell structures). The reproducible synthesis route for Au-coated, high moment, cobalt nanocrystals presented here opens up possibilities for a number of biomedical applicati...
