Abstract
The dependence on diverse microstructural parameters of the switching fields linked to the structures formed, due to exchange interactions, at the grain boundaries is investigated. Also, we have followed the ev olution with the increasing demagnetizing fields of systems formed by many exchanged coupled grains which clearly revealed that the occurren ce of collective demagnetization processes plays a major role in the c oercivity of this kind of systems.
