Abstract
The compositional dependence of the electromagnetic wave absorption properties of barium ferrite (BaFe12 O19) in which Ti and Mn were substituted for Fe, was investigated .Single phase M-type structure was obtained for BaFe12-x(Ti0.5Mn0.5)xO19 sintered samples with composition 0≤x≤4.5 . The frequency dependence of reflection loss (R.L) obtained a minimum value of -21dB for the x-band frequency range (8-12GHz), and give a band width greater than 1GHz in the same frequency range . The grain size of the prepared powder were between ( 7.05-12.06 µm) .Barium ferrite-resin composites with 30,40,and 50 mass% ferrite exhipted a wide band width with R.L Keywords
