Abstract:	Temperature dependence of the Hall coefficient and the resistivity in Tl₂Ba₂CaCu₂O_y (TL-2212), Tl₂Ba₂Ca₂Cu₃O_y (Tl-2223) and Cu_0.7C_0.3Ba₂Ca₃Cu₄O_y (Cu-1234) have been measured under high pressure up to 6 GPa. The values of the intrinsic T_c enhancement not related to charge transfer by applied pressure were estimated to be 0.8K/GPa for the Tl system and 1.1K/GPa for Cu-1234.
