Magnetic nanostructures based on self-organization

Published on April 23, 2012

This video briefly summarizes the final step of the preparation of magnetic nanoparticles and magnetic antidot arrays, as well as their characterization. Based on chemophysical processes, magnetic nanostructures are prepared. Initial steps of the chemophysical route employed for preparation of the nanoparticles are presented in a further video.

Prof. Paul Ziemann leads the Institute of Solid State Physics at the University of Ulm, Germany. His research interests include the properties of metallic nanostructures with an emphasis on transport and magnetic behavior. Furthermore, unconventional nanolithography based on the self-organization of diblock-copolymers and colloids, the preparation of thin films and their properties, the effects of medium-energy ion bombardment, and low temperature elastic and inelastic tunneling spectroscopy of adsorbed organic molecules complement the research activities. Prof. Ziemann is an Associate Editor of the Beilstein Journal of Nanotechnology.

PD Dr. Ulf Wiedwald is a principle investigator at the Institute of Solid State Physics of the University of Ulm. His research interests focus on the preparation of metallic nanostructures and thin films, as well as their electronic and magnetic properties. Based on chemical approaches, he prepares self-assembled layers of magnetic nanoparticles, particle–film hybrids, and antidot arrays, and characterizes their properties by various X-ray spectroscopy techniques, including X-ray magnetic circular dichroism.
