Nanosized Co0.5Zn0.5Fe2O4 and Cu0.5Zn0.5Fe2O4 were prepared using Co-precipitation method. Using a combination of x ray diffraction, Mössbauer studies and DC magnetization, the magnetic properties of nano sized Co0.5Zn0.5Fe2O4 and Cu0.5Zn0.5Fe2O4 have been studied. Although the preparation conditions were kept same, the particle size of Cu0.5Zn0.5Fe2O4 (2.4nm) were smaller than that of Co0.5Zn0.5Fe2O4 (5.8nm) as the formation of Cu0.5Zn0.5Fe2O4 is more exothermic in nature that the formation of Co0.5Zn0.5Fe2O4. The dependence of DC magnetization on particle size and cation distribution have been studied.

Using a combination of X-ray diffraction, room temperature/low temperature Mössbauer studies and d.c. magnetization, the structural and magnetic properties of nano-sized Cu 0•25 Co 0•25 Zn 0•5 Fe 2 O 4 , prepared using the coprecipitation method at different seeding temperatures, have been studied. Formation of α-Fe 2 O 3 in these samples is observed to be very sensitive to the seeding temperature and is totally suppressed at a seeding temperature of 333 K. These results are explained in terms of the rate of coprecipitation of the different components as a function of temperature. Since α-Fe 2 O 3 is antiferromagnetic, the presence and quantity of this impurity is also observed to deteriorate the overall magnetic properties of the spinel phase.
