Preparation and Characterization of Iron incorporated Silicon Carbide Foam prepared via Polymer Precursor Route

In the present study, Iron incorporated Silicon Carbide foam (Fe-SiC) were prepared via polymer precursor route using optimized template method. X-ray diffraction confirms the formation of Fe-SiC with traces of Fe3Si which may have induced the ferromagnetism in Fe-SiC. Microstructural study of Fe-SiC foam shows large variation in the range of pore size distribution. It is evident from SEM images that foam have open cell structures. Magnetic properties of Fe-SiC foam has also been investigated and compared. Addition of Fe induces the ferromagnetism in SiC which is very stable even at room temperature. Low coercivity in FeSiC and stability of ferromagnetism makes Fe-SiC suitable as soft Diluted magnetic Semiconductors (DMS) for device fabrication.
