Abstract
The partial substitution of Fe for Cu on the electrical and magnetic p roperties of (Bi1.6Pb0.4)(Sr1.8Ba0.2) Ca-2(Cu1-xFex)(3)O-y (0 less tha n or equal to x less than or equal to 0.05) has been investigated by e lectrical resistance, magnetic a.c. and static susceptibilities measur ements. The superconducting transition temperature T-c decreases with increasing Fe concentration and the samples are characterized by a lin ear temperature dependence of the electrical resistance above 2T(c). T he excess conductivity was analyzed. The inter- and intragrain critica l temperatures are affected differently. Static susceptibility yielded the effective magnetic moments corresponding to the high spin state o f Fe3+.
