MAGNETIC NANOPARTICLES, SYNTHESIS, ORDERING AND PROPERTIES

摘要: Abstract Polyol methods to synthesize nanoparticles and their arrays are firstly described. Magnetic self-assemble under particular conditions into spherical superstructures, like CoNi nanoparticles, or planar structures with hexagonal ordering, FePt nanoparticles. Particles structurally analysed by techniques TEM, X-ray, etc. characterization is performed VSM magnetomer as a function of the size paying attention transition from multidomain single-domain structures. Later on, magnetic exchange coupling effects discussed including temperature dependence parameters coercive bias fields, well influence field zero-field cooling processes. Finally, polymers consisting embedded PVC polymeric matrix prepared magnetically analysed.
