Characterization of thin YBaCuO films grown by coevaporation

Conference · · IEEE Trans. Magn.; (United States)
OSTI ID:6086234
Thin films of the Y/sub 1/Ba/sub 2/Cu/sub 3/O/sub x/ superconductor have been grown by coevaporation and post annealing in oxygen on substrates of (100) SrTiO/sub 3/, (100), MgO, and (100) Yttria-stabilized Zirconia. Films grown on SrTiO/sub 3/ show evidence of both a- and c-axis growth normal to substrate and strong in-plane order. Films on MgO show c-axis growth without any in-plane order, indicative of fiber texture. Transition temperatures of the films on MgO are depressed compared to those on SrTiO/sub 3/, but by using higher post-anneal temperatures the authors are able to improve the superconducting behavior of MgO samples.
