Abstract:
The objective of the present work is to study the effect of rare-earth (RE)
doping on the superconducting properties of (Bi,Pb)-2212 system and to develop
novel superconductors in the system with improved properties, especially,
the self- and in-field critical current densities so as to use them for practical
applications. This dissertation describes a range of findings in Bi-based
superconductor using the cationic substitution of rare earth (RE) elements.
Most of the experiments reported here take advantage of the difference in the
valency and ionic radii of dopant and doping site.
