Samples of Ru1-xMxSr2GdCu2O8, with M = Ti, V and Nb; and 0 ≤ x ≤ 1, were synthesized to shed light on the role of the RuO2 planes in this 1212-type compound which is a ferromagnetic superconductor (Tc = 10-40 K) when x = 0. We show that the ferromagnetism and the superconductivity are weakened for M = Ti and Nb, and enhanced for M = V, although superconductivity is suppressed for all samples of higher doping levels (x > 0.2). Jonker analysis of the high-temperature electrical properties of RuSr2GdCu2O8 shows that it falls within the characteristic range for other known superconductors.
