Abstract

We have studied the multiharmonic ac susceptibility response of HgBa2Ca4Cu5Oy (Hg:1245), a multilayered high-temperature superconductor (HTS) having two crystallographically inequivalent CuO2 planes in a unit cell with very imbalanced carrier concentrations. Vortex melting lines are well described by the commonly accepted model of melting with moderate anisotropy factors of 40-50, depending on the doping level. The diamagnetic response with applied fields parallel to superconducting (a,b) planes also shows a quite robust supercurrent along the c axis. Our results are also discussed in connection with contradictory models and experiments regarding the coexistence of superconductivity and antiferromagnetism in HTSs.
