摘要：
The Fe alloy-ferrite composites Fe-Co/Fe3O4 are synthesized by using disproportion of Fe (II) and reduction of Co (II) by Fe-0 in a concentrated and boiling KOH solution. The Fe alloy and ferrites are prepared in aqueous solution without any templet and surfactants at low temperature. Their structures and magnetic properties are investigated by X-ray diffractometer (XRD) and vibrating sample magnetometer (VSM). From the results of XRD, it is shown that the samples have b.c.c and f.c.c structure of Fe, and the spinel structures of the ferrite before calcinations; the samples have b.c.c and spinel structures after calcinations at 300 degrees C; and the samples have only f.c.c structure and the spinel structures calcined at 500 degrees C.
