Microwave and electrical behavior of Co2+ and Ru4+ ions substituted Ba-Sr sintered ferrite
Source abstract
Abstract
The complex permittivity and complex permeability of synthesized M-type hexagonal ferrite powders, Ba0.5Sr0.5CoxRuxFe(12-2x)O19 (x = 0.0, 0.2, 0.4, 0.6, 0.8, 1.0, 1.2) are measured at X-Band. The experimental results conclude that Co2+ and Ru4+ ions substitution enhances electromagnetic properties, rendering the use of ferrite for lossy applications. The acceleration in hoping mechanism between Fe2+ and Fe3+ ions leads to dominance of e′ and e″ over μ′ and μ″ along entire frequency band.
