摘要：
In this paper we report on the structural, electrical and magnetic properties of a systematic work performed on the synthesis of RuSr2(Nd,Ce)(2)Cu2O10-delta (Ru-1222) samples that differ for the number of annealings or sintering temperature in oxygen. This is done in order to highlight the different behaviours of properties as a consequence of the treatments. In particular, we deal with the development or loss of superconductivity after oxygen treatment. Further we discuss the influence of phase composition on superconductivity and magnetic ordering.
