Growth and properties of a multilayer system based on Y sub 1 Ba sub 2 Cu sub 3 O sub x and amorphous Y-ZrO sub 2
- Department of Physics, Chalmers University of Technology, S-412 96 Gothenburg (Sweden)
The growth of {ital c}-axis oriented Y{sub 1}Ba{sub 2}Cu{sub 3}O{sub {ital x}} thin films on an amorphous buffer layer of Y-ZrO{sub 2}, deposited on sapphire substrates, was investigated. Both films were grown by a pulsed laser deposition technique. A strong correlation was observed between the properties of Y{sub 1}Ba{sub 2}Cu{sub 3}O{sub {ital x}} and the thickness of the buffer layer. A {ital T}{sub {ital c}} of 89 K was obtained for an optimal buffer layer thickness of 9 nm. A model that adequately describes the film growth process was developed. A multilayer system of Y{sub 1}Ba{sub 2}Cu{sub 3}O{sub {ital x}} and amorphous Y-ZrO{sub 2} was grown and a {ital T}{sub {ital c}} of 87 K for the upper {ital c}-axis oriented layer was measured.
