Multiple heteroepitaxy and superlattice formation of LnBaCuO/YBaCuO system

Multiple heteroepitaxy and superlattice formation of high-T/sub c/ superconducting films were demonstrated. LnBaCuO/YBaCuO structures (Ln=Er, Nd) were realized as a preliminary stage. Superlattice formation made it clear that the crystal structure of the system strongly depends on the substrate materials. A
