Notes:
Magnesium ions were implanted into highly crystalline YBa2Cu3O7 (YBCO) thin films for the purpose of patterning. Films were implanted at doses corresponding to Mg contents of x=0.008, 0.02, and 0.04 in the formula YBa2(Cu1−xMgx)3O7. High temperature annealing (900 °C) of films implanted below the solubility limit was successful in obtaining single phase, Mg doped YBCO films with finite resistivities at 77 K and x-ray (005) rocking curve widths 〈0.15°. An electron probe microanalysis on a film patterned using Mg implantation revealed that lateral diffusion of Mg ions resulting from annealing was limited to only a few microns. The superior quality of a top layer film indicated that Mg ion implantation is suitable for multilayer patterning. © 1997 American Institute of Physics.
