Abstract

The transport properties of Ru1−xMxSr2GdCu2O8 (Ru-1212), with M = Ti, Rh and Sn for 0≤x≤0.2, have been studied. Both thermoelectric power (S) and resistivity (ρ) measurements are discussed and compared with those of Ru(Sr1−xLx)2GdCu2O8, where L is La and Na, with 0≤x≤0.10. The superconducting and normal state properties of Ru-1212 depend strongly on the type of dopant and the substitutional site. It is noticed that Tc is reduced for all doped compounds even for Ti, Rh and Na doping where a small decrease in S is observed. The behaviour of both S(T) and ρ(T) indicates that Ru-1212 superconductor is similar to other underdoped cuprate systems.
