Abstract:
The barium hexaferrite (BaFe12O19) is synthesized by the modified sol-gel method. The nanoparticle BHF with different average particle sizes have been prepared by using the high energy planetary ball mill. The X-ray diffraction (XRD) patterns reveal that all the materials crystallize to hexagonal crystal symmetry with P63/mmc space group. It is observed that the maximum magnetization decreases with the decrease in the average particle size of BHF. However, the maximum dielectric constant is found to be for the BHF with average particle size ~24 nm.

THE VISION
THE MISSION
ABOUT I-STEM
It has always been the basic tenet of the Government of India, in generously funding R&D efforts at academic institutions over the years, that facilities established through such support be made available to those needing them and qualified to make use of them for their own research work

However, this was never easy or straightforward for, among other reasons, there was no ready source of information of what facility was available and where. Thanks to the Web, it is much easier today to have a national and regional “inventory of resources”, so as to match users with the resources they need, and to do all this in an efficient and transparent manner.

This can lead to a leap in R&D productivity and greatly enhance the effectiveness of public investment. This is the motivation behind I-STEM.
