Synthesis and Magnetic Studies of Ultrafine Cobalt Ferrite Particles

Preparation of ferrites from the thermolysis of transition metal ferrioxalate precursors

“…This type of Mo È ssbauer spectrum has been reported in the literature for a cobalt ferrite having a particle size of 7.48 nm. 11 The existence of cobalt ferrite has been reaf®rmed by a powder XRD pattern of the ®nal thermolysis product (Fig. 6b).…”
