Magnetic and morphological characterization of magnetite nanoparticles with ligand shell — •Stanislav Emelianov, Maryam Youhannayee, and Mathias Getzlaff — Institute of Applied Physics, Heinrich-Heine-Universität, Düsseldorf, Germany

Magnetic properties of nanoparticles are of big interest for scientists due to its wide application in different field such as medicine. In our research, magnetic nanoparticles are obtained by wet chemical synthesis (coprecipitation) using the following procedure: Ammonium hydroxide drop wised in Ferric Chloride and Ferrous Sulphate mixed solution. All procedures of synthesis were carried out in the presence of nitrogen. In order to increase the biocompatibility and to decrease the toxicity of them, the particles have been coated with Aminosilane shell. We investigated magnetic properties of iron oxide nanoparticles by means of the transverse magneto-optic Kerr effect (TMOKE) which is based on the analysis of p-polarized laser beam intensity after interaction with magnetic samples. To evaluate physical and morphological characterization of the particles, DLS (Dynamic Light Scattering) and TEM (Transmission Electron Microscopy) techniques are involved, in order to determine shape, size and structure of the particles and to observe particle-cluster formation.
