Materials science became prominent and unique due to the emergence of nano science and nano technology. Among the materials, novel nano magnetic materials play a major role in the present explore, because its properties depend on preparation technique and microstructure and they are used in various modern technological devices. Especially ferrites are fully evolved in all fields of science, technology, and application, because they perform much better than other materials. Hence these materials have more importance and scope for the further development of electronics. The development of nanotechnology and nanoscience has made the study of nanoscale ferrite materials (with size 1-100 nm) are become interest in both the fundamentals and their application. For past 5-6 decades the investigate has increased on nano size materials, so the author proposed to develop simple method for the preparation of nanomaterial and study the characterization techniques of nano size materials.
