Abstract
A comparative study of the superconducting transition temperature (Tc), crystallographic structure, and 2 MeV He+ ion channeling in La1.85Sr0.15CuO4 films deposited on SrLaAlO4 single crystals, and SrLaAlO4 and CaNdAlO4 buffer layers is presented. Rutherford backscattering (RBS) and ion channeling experiments suggest a non-zero misalignment in the growth directions of the LSCO and the buffer layer. The Tc of the films on buffer layers is lower by 8-10 K compared to the Tc of the films on SLAO crystals. However, annealing of these films in ozone leads to a distinct enhancement in the critical temperature.
