Abstract
We have grown highly oriented LaBa2Cu3Oy (110)/Ag (111) bilayers on sapphire (112̄0). This structure constitutes a potentially excellent buffer layer for the growth of 1‐2‐3 ceramic oxides on sapphire substrates. This bilayer does not show superconductivity in resistive measurements. A DyBa2Cu3Oy film grown on this bilayer also exhibited (110) orientation.Keywords
