Abstract

Multilayers with a sequence of YBa₂Cu₃O₇/PrBa₂Cu₃O₇/YBa₂Cu₃O₇ have been sputtered epitaxially on [001] SrTiO₃ substrates. The heterostructures of these samples have been characterized by high-resolution electron microscopy, Rutherford backscattering and energy-dispersive X-ray analysis. The results indicate a correlation between the substrate quality and the microstructure of the thin films. Substrates with low defect density, a very smooth surface, and good orientation favour the epitaxial growth of all three layers. The chemical composition across the interface changes within the dimension of one unit cell.
