Magnetic properties of cobalt ferrite/SiO2 nanocomposite

Synthesis and characterization of SrFe12O19/CoFe2O4 nanocomposites with core-shell structure

“…Among these magnetic materials, the hexagonal ferrites SrFe 12 O 19 , BaFe 12 O 19 , etc. and the spinel ferrites such as CoFe 2 O 4 , ZnFe 2 O 4 have been extensively studied for their potential applications in microwave devices, high-density magnetic recording, electronic devices and medicine [4][5][6][7]. The hexagonal ferrites have high saturation magnetization, large anisotropy field, and the spinel ferrites have strong anisotropy, high coercivity and moderate saturation magnetization at room temperature.…”

Synthesis and characterization of nano-sized cobalt ferrite prepared via polyol method using conventional and microwave heating techniques

“…Therefore a large number of research have been reported in the literature concerning with the preparation methods for such materials such as mechanochemical [8], post-laser deposition [9], combustion [10], hydrothermal [11], co-precipitation [12], sol-gel [13], and many other methods [14]. Nanocrystalline cobalt ferrite dispersed in silica has been prepared by mechanical alloying and subsequent heat-treatment [15]. Also magnetic nanocomposites of Co-ferrite nano-particles dispersed in silica * Corresponding author.…”

Structural, magnetic and dielectric properties of Zr–Cd substituted strontium hexaferrite (SrFe12O19) nanoparticles

“…Among these magnetic materials, the hexagonal ferrites SrFe 12 O 19 , BaFe 12 O 19 , etc. have been extensively studied for their potential applications in microwave devices, high-density magnetic recording, electronic devices and medicine [4][5][6][7]. These materials have good mechanical, chemical stability and high microwave magnetic loss [8,9].…”
