Abstract

The coexistence of superconductivity and ferromagnetism in 1212-RuSr₂GdCu₂O₈ is unique among high-T_c materials. Samples of Ru_{1 - x}M_xSr₂GdCu₂O₈, 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 x<0.15 whereas that of Nb extends to full substitution. In all cases superconductivity is lost at higher substitution levels (x>0.2), however with vanadium substitution the T_c 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.
