X-ray diffraction analysis and occurrence of multiple phases in Bi-Sr-Ca-Cu-O superconductors
N D Kataria Mukesh Kumar V S Tomar V N Ojha G S N Reddy K C Nagpal A K Gupta
Starting composition 1112 for Bi-Sr-Ca-Cu-oxide yields multiphase super-conductors with the proportion of constituent phases depending sensitively on the annealing temperature. The R-T curves show zero resistivity and the transition corresponding to
