Nuclear and magnetic study of Cobalt, Manganese and Copper Ferrite nanoparticles obtained by a new electrochemical method
In the last decade, nanoparticles have attracted great interests in the scientific community due to their optical, electrical and magnetic properties. Cobalt ferrite has focused attention for its high crystalline anisotropy, high coercivity and moderate saturation magnetization, but most of its magnetic properties strongly depend on the size and shape of the nanoparticles, which are closely related to the preparation method. A new methodology based in the electrochemical synthesis has been developed in order to controlling particle size in the range 20-40 nm. We propouse a neutron diffraction study of particles obtained by this new method in order to localize the cobalt and iron atom in the octahedral and tetrahedral sites; relate the nanoparticle size with the magnetic behaviour and study the role of cobalt through the subtitution of this atom by nickel and manganese.
