Abstract

High quality HgBa₂CaCu₂O_x (Hg-1212) films have been synthesized on yttria-stabilized ZrO₂ substrates by using YBa₂Cu₃O₇ (YBCO) as a buffer layer. These films with Hg-1212 as the major phase were found to possess Tc (R equals 0) > 115 K and Jc approximately 10⁶ A/cm² (at 77 K). The X-ray diffraction patterns indicated that the obtained films have an in-plane epitaxial structure with the c-axis perpendicular to the film surface. The morphological investigations on the film surfaces have revealed the occurrence of layered spiral-like growth features. The influence of the YBCO buffer layer on the growing of Hg-1212 films is discussed.
