A phase diagram approach to superconductivity and magnetism in rutheno-cuprates
- 1. Univ. Bayreuth, Physikalisches Inst., Bayreuth (Germany)
Description
The layered rutheno-cuprates RuSr2LnCu2O8 (Ru-1212 structure) and RuSr2(Ln1+xCe1-x)Cu2O10 (Ru-1222 structure; Ln=lanthanide or Y for both structures) consist of pairs of CuO2 planes alternating with perovskite-like sheets of vertex sharing RuO6 octahedra. Samples of Ru-1212 and Ru-1222 materials were known to show both superconducting and magnetic transitions. However, these perovskite-like sheets are also the characteristic structural feature of some strontium ruthenates. The presence of such impurity phases and an apparent dependence of superconducting and magnetic properties on sample preparation conditions made it difficult to attribute the ordering phenomena to the Ru-1212 and Ru-1222 phases. Here we report on investigations of the phase equilibria in the system Sr-Gd-Ru-Cu-O and on a precursor route to the synthesis of RuSr2GdCu2O8 involving Sr2GdRuO6 and CuO. (orig.)
