Chemical-Deposited Biaxially Textured Oxides YBCO, Y2O3 and LZO as Functional Layers for 2G HTSC Tapes

Abstract—2G HTSC tapes YBCO/LZO/Ni-5W and YBCO/Y2O3/LZO/Ni-5W with the minimum number of layers are obtained. Heteroepitaxial structures (layers La2Zr2O7, Y2O3 and YBa2Cu3O7) are formed by chemical deposition from a solution and chemical vapor deposition. Their textural quality is confirmed by XRD. The influence of the layers on each other is shown. Many factors for improving the quality of the 2G HTSC tapes obtained by chemical methods are considered.
