Title: Influence of multi-walled carbon nanotubes (MWCNTs) volume percentage on the magnetic and microwave absorbing properties of BaMg{sub 0.5}Co{sub 0.5}TiFe{sub 10}O{sub 19}/MWCNTs nanocomposites

Abstract

Graphical abstract: Reflection losses of (a) doped barium hexaferrite, BaMg{sub 0.5}Co{sub 0.5}TiFe{sub 10}O{sub 19}, sample and their nanocomposites with (b) 4 vol. (c) 8 vol. and (d) 12 vol.% of MWCNTs are presented. - Highlights: • BaMg{sub 0.5}Co{sub 0.5}TiFe{sub 10}O{sub 19}/MWCNTs nanocomposites were synthesized. • The structural, magnetic and microwave absorption properties were investigated. • The microwave absorption is strongly influenced by volume percentage of MWCNTs. • The nanocomposite with 8 vol.% of MWCNTs can be proposed as a wideband absorber. - Abstract: In this study BaMg{sub 0.5}Co{sub 0.5}TiFe{sub 10}O{sub 19}/MWCNTs nanocomposites with different amount of MWCNTs (0, 4, 8 and 12 vol.%) were synthesized. Here, the X-ray diffraction (XRD), Fourier transform spectroscopy (FTIR) and scanning electron microscopy (SEM) were used to demonstrate the structural and morphological characteristics of the prepared samples. XRD along with FTIR examinations exhibited that the nanocomposites were successfully synthesized. Vibrating sample magnetometer (VSM) showed the relatively strong dependence of saturation magnetization and coercivity on the volume percentage of MWCNTs. The microwave evaluation also confirmed that the complex permittivity of nanocomposites could be enhanced by adding MWCNTs. Finally, the nanocomposite with 8% vol. of MWCNTs exhibited the best microwave absorption performance among the samples.
