Abstract

DyBa₂Cu₃O₇-thin films (DyBCO) prepared by thermal co-evaporation are an attractive alternative to YBCO for the use in RF devices. Large area, double sided DyBCO films have been grown on LaAlO ₃ and MgO substrates which are frequently used for RF filter designs. Due to an enhanced transition temperature T_c of 90 K compared to YBCO (typical 88 K), at 77 K DyBCO films exhibit an about 20% lower surface resistance than YBCO, while the power handling capability is comparable. Beyond that, DyBCO films are chemically much more stable and under humid conditions and the long-term degradation behavior is greatly improved.
