Studies on development of novel rare earth doped (Bi, Pb) - 2212 superconductors with enhanced properties

The thesis reports the development of novel rare earth substituted (Bi, Pb)-2212 superconductors with highly enhanced Tc, self- and in-field superconducting properties. The findings are quite promising and contribute significantly towards the understanding of rare earth doped (Bi, Pb) - 2212 superconductors and can be exploited for conductor applications in self - and in-fields at relatively high temperature of 64 K, the freezing point of liquid nitrogen.
