摘要：

This paper reports some results on the synthesis and characterization of cobalt, iron and cobalt-iron nanoparticles. The nanoparticles have been synthesised by polyol method and the obtained magnetic nanoparticles have a superparamagnetic behaviour. The morphology and size of the nanoparticles were studied by scanning electron microscopy (SEM) and dynamic light scattering (DLS). Compositional analysis of all the samples was conducted by EDS (energy dispersive X-ray analysis). The structure of the nanoparticles was examined by X-ray diffraction (XRD). Magnetic characteristics of the obtained nanoparticles were determined at room temperature by using a vibrating sample magnetometer (VSM), in an external magnetic field of 600 kA/m.
