摘要：

Epitaxial Tl2Ba2CaCu2O8 films were prepared on (1102BAR)Al2O3 with (100) CeO2 buffer layers. The Tl2Ba2CaCu2O8 was epitaxially oriented with its c axis perpendicular to the substrate surface and [100] Tl2Ba2CaCu2O8 aligned with [100] CeO2 and [2201BAR] Al2O3. The films exhibited T(c) of 97-98 K as measured both inductively and by ac magnetic susceptibility. Direct transport critical current density J(c) at 75 K was 2.8 X 10(5) A/cm2.
