Abstract:
Magnetic properties of the material with more than two crystal phases are found better as compared to that of single crystal phase material. Hence, nanocompositeswith different weight percentages of Barium Hexaferrite (BaFe12O19/BHF) in Barium Titanate (BaTiO3/BTO) matrix have been prepared. The X-ray diffractionpatterns of BHF, BTO and nanocomposites reveal the absence of other secondary crystal phases. The Raman spectra analysis supports to the XRD patterns analysis.The presence of both BHF and BTO crystal phases in the nanocomposites have been confirmed by the high resolution transmission electron microscopy. Interestingly,the nanocrystalline BTO exhibits weak ferromagnetic behavior. Magnetic interaction between BTO and BHF in the bi-magnetic BTO-BHF composite has beenobserved

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.
