Abstract
We present studies of the magnetic properties of core-shell iron-iron oxide nanoparticles. By combining Mossbauer and X-ray absorption spectroscopy we have been able to measure the change from a Fe3O4-like to a gamma-Fe2O3-like composition from the interface to the surface. Furthermore, we have observed exchange interactions across the core-shell interface. (C) 2003 Elsevier B.V. All rights reserved.
