Abstract

We studied the T_c-suppression by Cu-site substitution in Bi₂Sr_cCa_1-xY_x(Cu_1-xM_x)₂O_8+δ (Bi-2212) with M-Fe,Co,Ni,Zn and in Bi₂Sr_1.6La_0.4Cu_1-zM=O_6+δ (Bi-2201) with M=Co,Zn under variation of the hole concentration p. We found a distinct behaviour between the underdoped and overdoped side of the T_c-p phase diagram. Only in the overdoped regime, T_c is scaling as T_c (p, z)-T_c (p,0)g(z) with a p-independent scaling function g(z). We demonstrate the universality of this distinction in p-type high-T_c cuprates by comparison with publications on the La-214 and Y-123 systems and apply the scaling law to compare Bi₂Sr₂-Ca(Cu_1-xCo_x)₂O_8+δ with the intercalation compound IBi₂Sr₂Ca(Cu_1-xCo_x)₂O_8+δ- The results are discussed from the viewpoint of Abrikosov pair breaking, localization and phase fluctuations.
