Abstract

Chlorine-containing (Sr,Ca)₃Cu₂O_4+δCl_2-y (0212-Cl) superconductor is the high-T_cCu-oxide superconductor (HTSC) with T_c=80 K and was synthesized under high-pressure and high-temperature. The 0212-Cl has double [CuO₂] planes and the apical oxygen are replaced by Chlorine. We measured the resistance of 0212-Cl under high pressure using a diamond-anvil cell up to 13.3 GPa and two-terminal ac-method to investigate the pressure dependence of T_c. T_c of 0212-Cl increases gently with increasing pressure.
