• 論文の詳細を見る

• High-quality epitaxial Tl_2Ba_2CaCu_2O_8 superconducting thin films have been grown on NdGaO_3 (001) by a two step process. One film, annealed at 850℃, shows interdiffusion of Ga by secondary ion mass spectroscopy, resulting in an incomplete AC susceptibility transition at 80 K. For films annealed at lower temperature, excellent crystallinity and transport properties were obtained. Ground plane substitution of the film in a 5 GHz microstrip resonator indicated worse microwave performance than similar films on LaAlO_3 (001) substrates. The 2.3 GHz resonator made from the film on NdGaO_3 gave significantly worse quality factor (Q) values (1850) than those made on LaAlO_3.
