It was shown that, when without magnetic field or MFD lower than 2Tesla, spheric cobalt ferrite nanoparticles was obtained, and when MFD was equal or above 4Tesla, claviform cobalt ferrite nanoparticles appeared. With the increase of MFD, much claviform cobalt ferrite nanoparticles was obtained, and the crystallization of cobalt ferrite nanoparticles became better, also the magnetic properties such as remanence magnetism, saturation magnetism and squareness ratio were increased remarkably. The remanence magnetism of cobalt ferrite nanoparticles prepared in 10Tesla magnetic field was 15 times to that without magnetic field, and saturation magnetism was elevated by 1.44 times. Based on the theory of magnetic aggregation and critical magnetic domain, the mechanism how the high static magnetic field affect the shape, crystallization degree and magnetic properties of cobalt ferrite nanoparticles by coprecipitation-phase transform way was discussed.
