Summary:In this research, M-type Mn-Zr doped Ba-ferrites powders with a general chemical composition of BaFe10.6(ZrxMn1-x)O19 ( x= 0, 0.2, 0.4, 0.5, 0.6, 0.7, 0.8, 0.9, 1) were synthesized and prepared by a solid state method, and were then mixed with anAraldite + hardner and processed into polymer matrix composite specimens. Phase analyses of synthesized samples wereperformed by an XRD technique and magnetic properties of the composite specimens were measured using a hysteresis graphsystem. EM absorbtion characteristics of the composite samples in the (8-12 GHz) frequency ranges were determined using aVNA system.Among the compositions investigated in the present work, the highest absorbtion of -11.25 dB accured in BaFe10.6Zr0.28Mn1.12O19 (x= 0.2) at a frequency of 8.4 GHz. Based on EM absorbtion behaviors and magnetic properties, BaFe10.6Zr0.28Mn1.12O19 is classified as a potential EM absorber material.
