摘要：

Epitaxial growth of 1-2-3 superconductor films is reported on a new substrate material that possesses desirable dielectric properties. Magnetron-sputtered EuBa2Cu3O7-yfilms on YAlO3(001) show excellent properties with a Tcof 91 K. Films are epitaxially grown with the c-axis oriented normal to the surface, and the a- and b-axes ordered in the plane. The high-frequency (50 GHz) surface resistance of a film is 2 mΩ at 30 K. The dielectric constant of YAlO3is 16. The dielectric loss tangent at 10 GHz is as low as 7.3×10-5at 300 K and 2×10-6at 40 K. YAlO3-based films have considerable potential for high-frequency application. © 1990 IOP Publishing Ltd.
