Properties of HTS YBCO thin films deposited on tilted NdGaO3 substrates
Thin YBa2Cu3O7 films were fabricated by 2-opposed DC magnetron sputtering onto NdGaO3 substrates, tilted from standard (110) orientation by 0–26°, and their surface morphology and electrical characteristics were investigated. Normal state resistivity (at 295K) and microwave surface resistance (at 77...

| description | Thin YBa2Cu3O7 films were fabricated by 2-opposed DC magnetron sputtering onto NdGaO3 substrates, tilted from standard (110) orientation by 0–26°, and their surface morphology and electrical characteristics were investigated. Normal state resistivity (at 295K) and microwave surface resistance (at 77K and ∼8GHz) of the films demonstrated anisotropy, introduced by the tilted substrate, and some improvement of the superconducting parameters of the films was observed at small tilt angles (θ∼1.5–3°). The increase of the microwave surface resistance at high tilt angles for the current tracks, perpendicular to the steps of the substrate, was described in the framework of a simple model, which takes into account the complex conductivity of the film and the weak links between the film terraces. |
