中文摘要	The effects of high magnetic field (10T) on the products obtained by calcination of Co-Fe LDH precursors at different temperatures were investigated. The XRD results indicated that Fe-III substituted for Co-III in Co3O4 to yield (CoCoFeO4)-Co-II-Fe-III-O-III under the calcination of Co-Fe LDH precursors at 400 degrees C. The products obtained by magnetic field annealing at 400 degrees C had a porous plate-like morphology, whereas the products without magnetic field annealing were composed of nanoparticles. It was seen that Co Fe2O4 phase could be formed at low temperature (about 500 degrees C) under the magnetic field annealing. The grain size of products obtained by magnetic field annealing at 800 degrees C was larger than that of zeromagnetic field. It was found that the saturation magnetization was significantly enhanced after magnetic field annealing, especially at lower temperature (<= 600 degrees C). The possible reason for the effects on the microstructure and magnetic properties of products obtained by magnetic field annealingwasdiscussed.
