摘要：

We report on a first implementation of a design which provides a significant reduction of AC losses in YB(2)Cu(3)O(7-delta) (YBCO) coated conductors (CCs) without mechanical twisting. The conductor is composed of two diffusively bonded silver clad commercial CCs with zigzag patterned filaments partially separated by a dielectric layer. We produced three fully bonded samples with 500 mu m wide filaments using three-stage photolithography and wet chemical etching. A tenfold reduction of AC losses at frequencies between 20 and 400 Hz was observed, while transport measurements and magneto-optical imaging showed no degradation of T(c) and a low contact resistance of similar or equal to 10(-8) Omega cm(2) between Ag and YB(2)Cu(3)O(7-delta).
