Chapter 3 Magnetic Properties of the Size-Controlled Mn-Zn Ferrite

Ferrite nanoparticles find important applications in heat transfer devices, drug delivery systems and in medical diagnostics [1-4]. Nanosize particles of ferrites can be prepared using various synthesis techniques namely, ballmilling [5], citrate precursor [6], hydrothermal [7], coprecipitation [8,9] and other chemical methods [10].
