Structure and magnetic properties of cobalt ferrite foam with low mass density

It is extremely desirable but challenging to develop a facile synthesis to directly prepare permanent magnet foam with high coercivity (Hc) and low mass density to meet the requirements of advanced magnets in modern industry. In this work, we developed a facile strategy to synthesize cobalt ferrite...
