This paper deals with the development and characterization of nickel-zinc spinel ferrite (Ni (1-δ) Zn δ Fe 2 O 4 ) for microwave absorption at 2⋅4 GHz (ISM band). The ferrite powder was prepared by dry attrition and sintering process. Complex permittivity and permeability of the prepared sample have been determined by measuring its scattering parameters with the help of a vector network analyser. The measured parameters have been used to determine its wave absorption properties over a frequency range 2⋅1-2⋅6 GHz.
