摘要：
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 (.) measurements are discussed and compared with those of Ru( Sr1-xLx)(2)GdCu2O8, 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 T-c 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.( T) indicates that Ru-1212 superconductor is similar to other underdoped cuprate systems.
