| dc.description | Inclined substrate deposition (ISD) is an effective method for the fast production of highly textured template films for YBa<sub>2</sub>Cu<sub>3</sub>O<sub>x</sub> (YBCO) coated conductors (CCs). By electron-beam evaporation of MgO targets, we deposited biaxially textured ISD-MgO films with φ-scan full-width at half maximum (FWHM) of ≈10° on flat metallic tapes. Cube-on-cube epitaxial growth was demonstrated for YBCO grown on ISD-MgO buffered metallic tapes with an SrRuO<sub>3</sub> buffer. A transport critical current density of J<sub>c</sub>> 1.6 × 10<sup>6</sup> A cm<sup>−2</sup> was measured at 77 K in self-field on short-length flat-tape CCs produced with the ISD architecture. We have grown biaxially textured ISD-MgO template films on round wire surfaces. An in-plane FWHM of 18° was measured on ISD-MgO deposited on cylindrical surfaces. CC wires with a low aspect ratio and, therefore, low AC losses, are highly desirable in order to facilitate cable winding without compromising the mechanical integrity or engineering current density of the CCs. This work discusses the prospects of using the ISD process to produce low aspect ratio round-wire CCs. |
