Abstract

We have synthesized and studied a series of high-T_c superconductors (HTSC) HgBa₂Cu_1-xZn_xO_4+δ (x = 0, 0.01, 0.02 and 0.03) from underdoping to overdoping state. Lattice parameter a increased with increasing nominal composition of Zn (x), similar to Zn-substituted (La, Sr)₂CuO₄ and YBa₂Cu₃O_6+δ, indicating a replacement of Zn for Cu. As x increased, T_c determined by susceptibility and resistivity decreased for all doping levels.
