| Résumé | We present the synthesis and magnetic properties of high quality uncoated and gold-coated iron oxide magnetic nanoparticles. The structural properties of these nanoparticles are investigated by transmission electron microscopy, UV–visible spectroscopy and X-ray diffraction. Experimental results and theoretical simulations indicate that the synthesized nanoparticles present a very good monodispersity, and well defined size and shape. The coercive field of these particles is identified by low-temperature first-order reversal curves and the results used in order to fit zero-field-cooled magnetization processes with theoretical models. The identification of the parameters in this analysis suggests that the coating process hardly affects the morphology and the overall magnetic properties of the cores inside coated particles. |
