Chemical co-precipitation method was used for the preparation of Co-ferrite nano particles. The particle size was about 18 nm. A magnetic anisotropy of Co-ferrite could be increased by applying an external magnetic field during the pressing of the nano particles before the final sintering. This anisotropy enhanced the squareness and the coercivity of investigated samples.
