Abstract
Strontium hexagonal ferrites with compositional formula Sr0.85La0.15(NiZr)xFe12-2xO19, where ‘x’ varies from 0.00 to 1.00 in steps of 0.25, were synthesized by auto-combustion method. Structural, magnetic, electromagnetic and microwave absorption properties of synthesized ferrites were studied. The vector network analyzer (VNA) was used to measure complex permittivity (ε′–jε′′) and complex permeability (μ′–jμ′′) in X-band (8–12.4 GHz) and Ku-band (12.4–18 GHz) frequency range. The minimum reflection loss curves were obtained using back metal plate method for analyzing absorption properties of the material. All the synthesized ferrites show maximum absorption in Ku-band for sample thickness in the range of 1.6–1.68 mm. These newly synthesized ferrites have great potential to be used as thin microwave absorber sheets with minimum reflection loss values in the range of –19.69 dB to −27.8 dB and bandwidth in the range of 680 MHz–1.25 GHz.
