Abstract
The typical ceramic method was used to synthesize the composition of M-type hexagonal ferrite Ba0.5Sr0.5CoxLaxFe12-2xO19 by substituting Co2+ and La3+-doping ions (0.0 ≤ x ≤ 1.0 with steps of x = 0.2). The phase-related information of composition was examined by X-ray diffraction (XRD). The microwave absorption of composed material was examined related to doping, thickness, and frequency from (8.2–12.4) GHz by using standard testing instrument. Mechanisms of impedance matching along with quarter wavelength matching have been used for calculation of microwave absorption of composed material. Enhanced microwave absorption of 97% was obtained with x = 0.2 at frequency of 10.75 GHz and thickness 1.9 mm. Also, absorption bandwidth of 0.07 GHz (− 10 dB ≤ RL ≤ − 20 dB) and 0.2 GHz (RL ≥ − 20 dB) was observed.
