Abstract

In the present study, permanently magnetic barium ferrite foams synthesized using a replication technique were characterized. Structural analysis have shown that the products are single phase of BaFe12O19 and pore sizes reach up to 1 mm in diameter with a significantly uniform distribution. Magnetic properties were examined and compared with that of a sintered compact sample. It was observed that magnets become slightly harder with porosity. Our findings reveal that these materials may be applied to different technologies and can be used for understanding the physical interactions of hybrid structures. (C) 2010 Elsevier B.V.
