Abstract

The coexistence of superconductivity and ferromagnetism in 1212-RuSr2GdCu2O8 is unique among high-Tc materials. Samples of Ru1 - xMxSr2GdCu2O8, with M = Ti, V and Nb; and 0≤x≤1, were prepared to elucidate the role of the RuO2 planes in this interesting layered 1212 cuprate. The solubility ranges of M = Ti and V are limited to x0.2), however with vanadium substitution the Tc increases from 20 K to 25 K. The ferromagnetism of the RuO2 layers is dramatically affected by the electronic configuration of the substituting ion, weakened for M = Ti and Nb and enhanced for M = V. These results indicate that the superconductivity and ferromagnetism are intimately linked to the layered architecture of this 1212 structure.
