"Synthesis, Characterization and Magnetic Properties of Colloidal Nanoparticles"

Presented by Daniela Zanchet, Brazilian Synchrotron Light Laboratory, Brazil

Friday, July 28, 2006, 10:00 am — Room 300

Colloidal magnetic nanoparticles have attracted much interest in the last few years owing to their fundamental interest and technological applications. The correlation of parameters such as morphology and crystalline structure of the particles with the resulting magnetic properties has been thoroughly investigated in several nanostructure systems, but many open questions remain to be answered. In particular, the intrinsic complexity of nanostructured materials makes a reliable correlation between experimental data and proposed theories difficult. In this aspect, colloidal nanoparticles are particularly interesting due to the possibility of varying different characteristics, such as size and structure, in a more independent and controllable way. In this talk, recent results about the synthesis and characterization of colloidal magnetic nanoparticles such as nickel, iron oxide and cobalt will be presented, and correlated with their magnetic properties.
