摘要：

A new 1223-type (Tl, V)-based superconducting layered cuprate (Tl1_xVx) Sr2Ca2Cu3O9 with x = 0.25 and 0.50 has been successfully synthesized in the nearly-pure form and identified by powder X-ray diffraction analyses. An excessive quantity of Tl is necessary for the preparation of the (Tl, V)-based 1223-type compound. Resistance and ac susceptibility measurements showed that the new (Tl, V)-based 1223 cuprate exhibits T-c above 110 K.
