Revised Fundamental Properties and Crystal Engineering of Spinel Ferrite Nanoparticles

Extensive research on ferrite-based materials and their application in field of electronics is of great importance in near future. In the last decade, several experiments have been conducted for developing different forms of ferrite-based materials through controlling its size, composition, and morphology. Such studies indicate that the chemical and physical properties of these materials can in principle be manipulated based on the desired application and are highly relevant from the technological point of view. However, the relationship between the closed structure and the composition of these advanced nanoscale materials is still debatable. In this chapter, the chemical structure of spinel ferrite nanoparticles has been studied using crystal engineering. It is quite evident that the change in the morphology of its particles and in the degree of defects alter their magnetic, optical and catalytic properties significantly. This makes these materials suitable for use in electronic devices such as high-density recording media and as a medical guide.
