Abstract
Strained multilayer thin films of YBa2Cu3O76/Nd1.83Ceo.i7CuO have been prepared by laser ablation deposition. For individual layers below a critical layer thickness of about 250A, coherency strain compresses the Nd1.83Ceo.17CuO lattice and expands the YBa2Cu3O75 lattice. The orthorhombic distortion in the YBa2Cu3O75 layers is also removed. Depending on their oxygen content, either the YBa2Cu3O75, or the Nd1.83Ce0.17CuO layers are superconducting in these multilayers. The strain-induced structural modification has a significant influence on the superconducting transition temperature and critical current density of the YBa2Cu3O75 layers. Zero field critical current densities as high as 1.lxlO7A/cm2 at 77K have been measured for the YBa2Cu3O7 -, layers.
