The iron hydroxide particles prepared above were coated with cobalt by surface adsorption-precipitation reaction. The low pH and Co〓 concentration of suspended system can prevent the nanoparticle from heterocoagulation. The saturation magnetization of MP particles with uniform cobalt hydroxide layer is 10％ higher than that of the α-Fe. And a close SiO〓 layer can improve the coercivity by about 92％.
