Double-sided Tl2Ba2Ca2Cu3O10 thin films based high temperature superconducting filter operating above 100 K

“…Compared to the conventional method of fabricating Tl-2223 films, the inter-phase based approach could avoid the volatility of T1 2 O and the intergrowth of other phases, which is critical for fabricating high-quality Tl-2223 films. The interested readers are referred to the relevant literature for details, 12 where a fabrication method of 10 mm  3 mm one-sided Tl-2223 film was introduced. Different from the fabrication method of the one-sided film, the two-sided precursor films were rotated horizontally and vertically at a constant speed to guarantee the uniformity of the two sides of the films.…”
