A novel ‘one-pot’ synthetic method for preparation of (Ni0.65Zn0.35Fe2O4)x–(BaFe12O19)1−x nanocomposites and study of their microwave absorption and magnetic properties

article i nfo Hard soft ferrite nanocomposites One-pot synthesis Spring exchange coupling Magnetic measurements Microwave absorption In this paper, we report a simple but novel aqueous solution based 'one-pot' method for preparation of (Ni0.65Zn0.35Fe2O4)x-(BaFe12O19)1 � x nanocomposites consisting of hard ferrite-soft ferrite phases. Nanocom- posites, having same compositions, have also been prepared by employing a physical mixing method. X-ray dif- fraction analysis showed the presence of nanocrystalline Ni0.65Zn0.35Fe2O4 and BaFe12O19 phases in the composites, prepared by both methods. However, transmission electron microscopic and scanning electron mi- croscopic analysis revealed that, nanocomposites, prepared by one-pot method, possessed better homogeneous
