摘要:

Superconducting Hg‐based cuprate thin films have been fabricated on (100) SrTiO3substrate using rf sputtering and post‐Hg‐vapor annealing. These films are dominated byc‐axis‐oriented Hg‐1223 phase as indicated by x‐ray diffraction and SQUID measurements. Using four‐probe technique, theTc,onsetwas found to be 130–132 K andJcwas up to 8.5×104A/cm2at 77 K and zero field. ©1995 American Institute of Physics.
