The adopted preparation method comprises the following steps: paper fibre or porous organism is used as a hard template; CoFeFe-LDH is synthesized in the surface and holes of the hard template and roasted to prepare the magnetic cobalt iron ferrite; as the function for fixing the houghite position is produced by the obstruction and adsorption of the hard template, the occurrence of the sintering phenomenon is greatly avoided, thereby preparing the magnetic cobalt iron ferrite with a consistent shape and even granularity.
