摘要：
In this study the samples were synthesized from a 2234 stoichiometric composition in order to obtain a large amount of pure 2212-BSCCO. The effects of Ni substitution on the properties of Bi-based Bi2-xNixSr2Ca1Cu2Oy superconductor with x = 0, 0.05, 0.1 and 0.2 were investigated by means of X-ray analysis (XRD), DC electrical resistivity and magnetic-hysteresis loop measurements. It has been found that the T-c (onset) transition temperature does not change independently of Ni content. In addition, J(c) values of the samples were calculated from the hysteresis loop measurement by using Bean's model, showing that J(c) decreases with increasing Ni substitution.
