Abstract
We report on the preparation and electrical resistivity, a.c. suscepti bility, d.c. magnetization, X-ray diffraction and scanning electron mi croscopy measurements of the Bi1.6Pb0.3M0.1Sr2Ca2Cu3Oy (M=W,Mo) superc onducting system. The results can be summarized as follows. (1) Doping of WO3-MoO3 increased the fraction of the high T(c) phase by reducing the amount of low T(c) phase. (2) Coupling between the grains is weak ened by doping. (3) The intragrain critical current density is not aff ected by doping.
