摘要：
The phases, size, shape, aggregation pattern and chemical composition of carbonyl Fe-Ni ultrafine particles prepared by thermal decomposition of the mixture of Fe(CO)(5) and M(CO)(4) were investigated by X-ray diffraction and electron microscopy. It was found that the main phase was gamma-(Fe-Ni), including a small amount of Fe3O4. The particle size was about 10 nm and the particles formed a fractal aggregation pattern whose dimension was 1.64. The composition varied from particle to particle, showing an average value of Fe44Ni56. The magnetic properties of the particles were examined with a vibrating sample magnetometer.
