Abstract
The effect of T1 substitution for Hg in the Hg-Ba-Cu-O system has been investigated for a wide substitution range. A single-layer system was maintained until 50% of T1 substitution, and above 50%, a double-laye r system was observed. T1 substitution brought about an overdoping sta te in the CuO2 plane, probably because (T1O)(+) was introduced for Hg2 +. A simple explanation for the change from a single-layer to the doub le-layer system is presented. (C) 1998 Academic Press Limited.
