Abstract:
In this work, a series of (Ni-Ag) co-doped SnO2 compounds i.e. Sn1-x-yNix AgyO2 (x = 0–0.12 and y = 0–0.12) compounds have been prepared by the solid-state reaction route. The x-ray diffraction patterns (XRD) indicate that these compounds crystallize to rutile phase with tetragonal structure. Temperature variation of magnetization (M-T) of these compounds indicates that the co-doping of Ni and Ag in place of Sn in SnO2 gives rise the increase in magnetization. One of the striking features observed from the M-T measurement is the relatively large Curie temperature (θ C ) in the order of 721.2 K and 675.7 K for Sn0.94Ag0.06O2 and Sn0.94Ni0.06O2 compounds. The θ C is found to decrease systematically upon Ni-Ag co-doping. The M-H curves at the room temperature indicate that the saturation magnetization, area under the hysteresis loop and the coercive field increases with the increase in (Ni-Ag) co-doping upto x = y = 0.06 (i.e. 6%). However, for further co-doping, these parameters were found to decrease

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.
