Abstract

The co-existence of different magnetic phases, (i.e. ferromagnetic, antiferromagnetic, paramagnetic) mixed on a nanostructure scale has a profound influence on the soft/hard magnetic behavior of the materials. The effects of thermal treatment of these multiphase systems has been examined and a strong interdependence found between the nanosructure and the exchange correlatio length.
