W-hexaferrite particles (Ba(Co 0.5Zn 0.5) 2Fe 16O 27) have been successfully synthesized using a combination of co-precipitation and mechanical milling. These particles possess excellent hexagonal shape and are well separated from one another. The complex permeability and complex permittivity of fer...
