In present research, we investigate microwave absorption properties of M-type hexagonal ferrite Ba0.5Sr0.5CoxLaxFe12−2xO19 (0.0 ≤ x ≤ 1.0; x = 0.2) compositions in X band developed using ceramic technique. Energy dispersive spectroscopy (EDS) spectra of different compositions are examined for composition details in frequency region (8.2-12.4) GHz. The doping of Co2+ and La3+ materials increase microwave frequency absorption, absorption bandwidth, reduces thickness & promotes impedance matching. Then, Scanning electron micrograph (SEM) confirm grain size adhere to microwave frequency absorption. The best reflection loss value of -43.73 dB is found with composition x=0.2, 1.9 mm thickness and at 10.75 GHz frequency..
