Structural, magnetic, microwave and ac induction heating study of Li_(0.35)Zn_(0.30)Co_(0.05)Fe_(2.3)O_4 integrated in multi-walled carbon nanotube matrix

摘要

Nanoparticles of Li_(0.35)Zn_(0.30)Co_(0.05)Fe_(2.3)O_4 are prepared by sol-gel method and integrated in the non-magnetic matrix of multi-walled carbon nanotubes (MWCNT). Structural and microstructure analyses of the prepared samples are investigated by X-ray diffraction, high resolution transmission electron microscopy and Raman spectroscopy. To study the magnetic behavior, dynamic and static hysteresis loops are recorded. The microwave absorption properties of the nanoparticle integrated in MWCNT matrix are observed and analyzed. The ac induction heating efficiency of the nanoparticles is estimated by calculating specific absorption rate.
