Abstract

Through hydrogenation and oxidation of rare earth-iron intermetallic compounds, Fe metal, alloy, or compound-based nano-composite powders were synthesised, their microwave absorption properties were characterized in a range of 0.5-40 GHz. They found to show good absorption properties in the rabge of 2-20GHz to reduce the interference problems induced by the application products.
