  title = {Laser deposition of biaxially textured yttria‐stabilized zirconia buffer layers on polycrystalline metallic alloys for high critical current Y‐Ba‐Cu‐O thin films},
  abstract = {<p>Pulsed laser deposition of yttria-stabilized zirconia (YSZ) layers on polycrystalline metallic alloy substrates is used to produce an intermediate layer for YBa<sub>2</sub>Cu<sub>3</sub>O<sub>7-δ</sub> (YBCO) thin-film growth. The desired (001) YSZ texture is obtained at 1.0 mTorr oxygen pressure and 70&thinsp;°C. Significant improvement in (001) texturing is demonstrated by using an ion beam to assist growth. Argon-ion-assisted growth produces layers with alignment of the in-plane crystal axes in addition to the (001)-normal texture. Highly <em>c</em>-axis-oriented biaxially aligned YBCO thin films can be deposited on these layers, with <em>T</em><sub><em>c</em></sub>(<em>R</em>=0)=92 K and <em>J</em><sub><em>c</em></sub> (77 K, <em>B</em>=0 T)=6×10<sup>5</sup> A/cm<sup>2</sup> and <em>J</em><sub><em>c</em></sub> (77 K, 0.4 T)=8×10<sup>4</sup> A/cm<sup>2</sup>. With further improvement of the YSZ texture, the YBCO current-carrying capacity of films on polycrystalline metallic alloys may approach that of films on single-crystal substrates.</p>},
