Growth and Properties of YBa sub 2 Cu sub 3 O sub 7 Thin Films on Vicinal and Polycrystalline MgO Substrates

The results of a study on the growth by laser ablation of YBa sub 2 Cu sub 3 O sub 7 thin films on polycrystalline and annealed vicinal (001)MgO substrates are presented. In both instances the films were found to grow predominantly with the c axis normal to the plane of the substrate, regardless of...

Zusammenfassung:	The results of a study on the growth by laser ablation of YBa sub 2 Cu sub 3 O sub 7 thin films on polycrystalline and annealed vicinal (001)MgO substrates are presented. In both instances the films were found to grow predominantly with the c axis normal to the plane of the substrate, regardless of the orientation of the MgO surface. In the case of the vicinal substrates the films were found to have superconducting properties comparable to those obtained with films grown on (001) oriented, annealed single-crystal substrates.
