Abstract:
Taking cue from the increase in the superconducting transition temperature (Tc)ofFe1þxSe via nominal(2 wt%) substitution of Cr instead of excess Fe, we have now extended our study with nominalsubstitution (r5 wt%) with other transition metals (Ni, Co, Fe, Mn, Cr, V and Ti) in place of excessiron. TheTcis found to increase (maximum11 K) or get suppressed depending on the substitutedtransition metal. Our studies indicate that the superconducting transition temperature depends on ionicsize of the transition metal and amount of hexagonal phase present as impurity.

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.
