Epitaxial T12Ba2CaCu20e thin films have been prepared on (001) LaA103 substrates by cc magnetron sputtering and a post-annealing process. X-ray diffraction (XRD) 8-28 scans, 4 scans and rocking curves proved that the thin films are strongly textured with the c axis parallel to the c axis of the substrate and epitaxially grown on the substrate. A critical current density of 7.6 x lo6 A cm-* at 77 K has been obtained in zero magnetic field, and the films have strong flux pinning force in high magnetic fields. When magnetic fields were applied perpendicular to the C M plane of the film, the critical current density dropped only by a factor of seven in a 4 T magnetic field and a factor of 15 in a 6.5 T magnetic field.
