摘要：

The evolution of the magnetic properties, and particularly of the coercive field, of aggregates of particles of pure and Co-modified iron oxides on packing is analyzed. When the interactions, evaluated with the DELTA plot area, increase, the coercivity of the Co-modified particles shows an anomalous behavior, which is imputed to a reduction of the canting of the magnetic moments in the surface layer.
