Abstract
The lattice parameters and ac susceptibility of Y1-xCaxSrBaCu2.9Ga0.1O 6+z (X = 0, 0.05, 0.1, and 0.2) are reported. T(c) decreases as a resu lt of (0.1) Ga substitution from 83 to 67.5 K but increases to 79.5 an d 80 K for x = 0.1 and 0.2, respectively. The present data in comparis on with those on Al and Co which have been shown to occupy chain sites suggest strongly that Ga also preferentially occupies the chain sites .
