Abstract

By measuring the magnetization hysteresis, we studied the critical current density, Jc, and irreversibility fields, Hirr, of a c-axis aligned Hg-Ba-Ca-Cu-O sample doped with Pb containing the Hg-1223 phase as the main phase. Anisotropy in ΔM was clearly observed in two different magnetic field directions. Even though the Hg-1223 phase contains three CuO 2 sheets, the Hirr vs [1-(T/Tc)] curve was located at roughly the same positions as those reported for the Hg-1201 and Hg-1212 phases, indicating that the higher Tc phase, i.e., Hg-1223, is advantageous to the other phases in practical uses.
