The partial substitution of Fe for Cu on the electrical and magnetic properties of (Bi1.6Pb0.4)(Sr1.8Ba0.2) Ca2(Cu1 - xFex)3Oy (O ≤ x ≤ 0.05) has been investigated by electrical resistance, magnetic a.c. and static susceptibilities measurements. The superconducting transition temperature Tc decreases with increasing Fe concentration and the samples are characterized by a linear temperature dependence of the electrical resistance above 2Tc. The excess conductivity was analyzed. The inter-and intragrain critical temperatures are affected differently. Static susceptibility yielded the effective magnetic moments corresponding to the high spin state of Fe3+. |
