Abstract
Resistivity and magnetic susceptibility of superconducting Bi0.25-y Sr0.25-y Ca2y Cu0.5O x (y=0.1, 0.125, 0.15) have been measured and compared with the results of X-ray powder diffraction. The volume fraction of the low-T c phase (T c∼75 K) decreases as the Ca concentration is increased and superconductivity attributed to the high-T c phase (T c>100 K) is observed. Resistivity of Bi0.125Sr0.125Ca0.25Cu0.5O x shows a sharp transition above 100 K and becomes zero at 97 K.Keywords
