摘要:
In order to study the influence of the texture and surface morphology of Ag substrates on the YBCO film properties, YBCO films were deposited on three different Ag substrates. The YBCO film deposited on Ag substrate annealed in vacuum has a poor texture and low J(C). in addition, the film is loose and unconnected. The YBCO films deposited on Ag substrate annealed in Ar atmosphere have strong c biaxial texture and higher J(C) 1.2x10(4)A/cm(2). The texture of YBCO film deposited on the cold rolled Ag substrate is not as strong as the texture of the film deposited on Ag substrate annealed in Ar atmosphere. Due to its smooth surface, the YBCO film deposited on the cold rolled Ag substrate still has higher J(C) of 1.5x10(4)A/cm(2).
