Abstract :
Temperature dependent dielectric spectroscopy data of magnetic fluids are presented. Under an applied magnetic field, the inner topology of the samples and thus their dielectric properties change. The first results provide evidence for the formation of chain-like structures, in agreement with small-angle X-ray scattering and computer simulations
