Effects of Sr-substitution on the structural and magnetic behavior of Ba-based Y-type hexagonal ferrites.

Highlights: [•] Sr-substituted Y-type hexaferrites synthesized by sol–gel method have been investigated. [•] Platelet grains with well defined hexagonal shape are suitable for microwave absorbers. [•] Saturation magnetization values were calculated by the law of approach to saturation. [•] Coercivity of a few hundred oersteds found for all samples is suitable for EM materials.
