Properties of YBa2Cu3Oy Films on BaSnO3 Layers

Toshiya Matsubara; Shinichi Ohashi; Atsuyoshi Takenaka; Takeshi Morimoto

We have investigated the potentiality of BaSnO3 as the buffer layer between a superconducting Y-Ba-Cu-O layer and a substrate. At first, the reactivities of some barium double oxides with the Y-Ba-Cu-O system were examined at the partial melt region (1050°C), and BaSnO3 was found to be the most stable. It was then confirmed that BaSnO3 formed a thin and dense layer on a (100)MgO single crystal by a CVD method. Superconducting films of YBa2Cu3Oy with critical current densities of up to 3 x 105A/cm2 in zero magnetic field at 77K were prepared on the BaSnO3 layers.
