Magnetic characterization of iron oxide superparamagnetic nanoparticles on surfaces — •Stanislav Emelianov, Maryam Youhannayee, and Mathias Getzlaff — Institute für angewandte physik, Heinrich-Heine-universität Düsseldorf

Nowadays Magneto-optic effects are widely used in magnetic research. Magnetic characteristics of thin films and nanoparticles properties are of big interest for scientists due to its wide application in different field such as medicine. In our experiment we investigate the properties of iron oxide superparamagnetic nanoparticles on surface applying SQUID and also the methodology and the setup 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. In our experiment superparamagnetic nanoparticles are prepared by wet chemical synthesis. It is a coprecipitation of Ferric Chloride and Ferrous Sulphate with Ammonium hydroxide. The obtained parameters are illustrated by means of hysteresis loops which indicate the relevant magnetic characteristics.
