Abstract

We report the broad and double resistive transition of Bi2Sr2-xInxCaCu2O8+x bulk samples. The two onset transitions are broad and within the transition range of Bi-2212. As indium concentration increases, there are slight significant changes in the average lattice parameters but the XRD peaks visibly broaden indicating large variation of c-axis lattice parameters. We conclude that the double resistive transition was due to In-doped Bi-2212 phase and pure Bi-2212 phase because indium was not fully substituted the Sr site of Bi-2212. Excess indium also favors formation of impurity phases that cause the broadening of the resistivity transition plots.
