摘要：

The polyol process is a suitable chemical route to synthesize noble metals and CoNi nanoparticles. Noble metal nanoparticles dispersions are obtained through steric or electrostatic stabilization. By acting on nature and concentration of the noble metal as nucleating agent, the CoNi particles mean diameter is varied over a wide range with accuracy and reproducibility as well. Such a size control enabled to afford a further insight into the growth of the particles and brought the opportunity to evidence original microwave magnetic properties.
