Fabrication, magnetic and microwave absorbing properties of Ba2Co2Cr2Fe12O22 hexagonal ferrites

• Ba2Co2Cr2Fe12O22 NPs were investigated magnetic and absorbing behavior.
• VSM measurements of NPs were showed the existence of superparamagnetism with very small coercivity and soft ferrite materials.
• Nanocomposites showed higher EM absorption frequency and wider absorption bandwidth.

We have investigated the magnetic and microwave absorbing behavior of Ba2Co2Cr2Fe12O22 Nano Particles (NPs)/polyaniline (PANI) and polyacrylonitrile (PAN) nanocomposite materials. Particles showed phase purity and crystallinity in powder X ray diffraction (XRD) analysis. Temperature dependence of magnetic parameters was observed. Microwave absorbing showed very broad and high reflection loss.
