Preparation and Properties of Porous Barium Ferrite

Article Preview

Abstract:

Nano-porous Barium ferrite (BaFe12O19) nanoparticles were synthesized by sol-gel technique using CTAB as template. The structure, morphology, and magnetic properties of samples were characterized by X-ray diffraction analysis (XRD), scanning electron microscopy (SEM) and vibrating sample magnetometer (VSM). The results show that particles size are about 45 nm to 65 nm. And the nanoparticles show a saturation magnetization (Ms) of 62.831 emu/g, a coercivity (Hc) of 5481.0 Oe and a remament magnetization (Mr) of 33.083 emu/g.
