Magnetic fluids are widely used in tech. and biomedical applications. Depending on the application, different properties of the magnetic fluids are of interest. To choose magnetic fluids for a specific application, a comprehensive characterization is needed. In this work various aq. magnetic fluids were systematically studied with regard to their physicochem. properties. Besides magnetic properties the chem. compn., zeta potential, core and particle size of the samples were detd. Among techniques like magnetization curve measurements or photon correlation spectroscopy novel methods like acoustic and electroacoustic spectroscopy were used, which allow size and zeta potential measurements esp. in highly concd. dispersions. Comparisons of the results obtained by the different methods show good agreements. Also, the magnetic relaxation was studied, which is of significance for a novel biomedical application. The complex requirements of magnetic fluids for this application are considered in more detail. [on SciFinder(R)]
