Abstract

Anisotropic bond model has been used to investigate the compressibility for the HgBa₂Ca_n-1Cu_nO_2n+2+δ (n=1, 2, and 3) under ambient pressure. The volume compressibilities are found to decrease linearly with increasing oxygen content and decrease systematically with the increase of n. The pressure dependence of T_c is analyzed in terms of pressure-induced charge transfer model. The calculation maximum values of T^max_c under pressure for optimally dopings and pressure coefficients of T_c are in agreement with the experimental results.
