摘要：

The formation of the (Ph, Cd)-1212 phase in the (Pb0.5Cd0.5)Sr(2)RCu(2)O(7) system was investigated systematically. It is found that the (Pb,Cd)-1212 phase can be formed for all R (R is a rare earth element) except La and Ce. The structure of (Pb0.5Cd0.5)Sr2TbCu2O7 is refined. The refined structure parameters are nearly the same as those of (Pb0.5Cd0.5)Sr2YCu2O7.
