| Abstract(in English) | We have fabricatedl YBCO/STO/YBCO structures, and studied the properties of the counter and base YBCO films. The trilayer structures ware prepared by PLD technique. In order to obtain reliable STO insulating layer, the mechano-chemical-polishing (CMP) method was introduced into the process. The procedure was that the STO surface was polished by CMP and etched by ECR after for cleaning, then STO/YBCO bilayer was fabricated on YBCO/STO bilayer. Typical base and counter YBCO layers showed Tc = 91.2K and Jc(77K) = 3.6 × 10^6A/cm^2, and Tc = 87.5K and Jc (77K) =3.2 x 10^6A/cm^2, respectively. The insulation resistance between the base and the counter eletrode was more than 10MΩ at 77K. As a result, a basic structure for multilayer device was prepared with good superconducting properties. |
