•Microwave properties of Co–Ru substituted M-type Ba–Sr hexagonal ferrite are investigated as a function of frequency and substitution at X-band.•The static I–V characteristics have been studied as a function of substitution.•Different compositions are suggested for practical applications as microwave absorber and electromagnetic shield•Microwave and electrical properties are correlated to microstructure.
The microwave absorption of Ba0.5Sr0.5CoxRuxFe(12−2x)O19 (x=0.0,0.2,0.4,0.8,1.0) ferrite has been investigated as a function of frequency, substitution and thickness. The static I–V characteristics have been studied as a function of substitution. The results exhibit reflection loss of −12.02 dB at 9.0 GHz in x=0.2. The electrical current density increases at higher substitution. The microwave and electrical properties show dependence on microstructure. The ferrite compositions for different electromagnetic applications are also suggested.
