Effects of divalent ions substitution on the microstructure, magnetic and electromagnetic parameters of Co2W hexagonal ferrites synthesized by sol–gel method.

Highlights: [•] W-type hexagonal ferrites substituted with different divalent ions have been investigated. [•] Platelets like grains with hexagonal shape are suitable for microwave absorbers. [•] Saturation magnetization was calculated by the law of approach to saturation. [•] The low value of coercivity for the investigated sample is favorable for EM materials. [•] The materials are good for suppression of EMI and as radar absorbing materials (RAMs). [ABSTRACT FROM AUTHOR]
