Microwave and electrical characterization of M-type Ba0.5Sr0.5COxRuxFe(12-2x)O19 hexaferrite for practical applications

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. (C) 2014 Elsevier Ltd. All rights reserved.
