Abstract

The Vapor-Liquid-Solid (VLS) growth technique, which combines the Pulsed Laser Deposition (PLD) method with the Liquid Phase Epitaxy (LPE), is expected to achieve both high deposition rate and high crystallinities. To apply superconducting Coated Conductors (CCs) for applications such as superconducting magnets, it is indispensable to introduce Artificial Pinning Centers (APCs) such as BaHfO <sub xmlns:mml="http://www.w3.org/1998/Math/MathML" xmlns:xlink="http://www.w3.org/1999/xlink">3</sub> (BHO). In this study, we aim to achieve high deposition rate, crystalline orientation, and APCs by using VLS growth technique. As a result, we confirmed that BHO was introduced without deterioration of crystallinities. Furthermore, critical current density J <sub xmlns:mml="http://www.w3.org/1998/Math/MathML" xmlns:xlink="http://www.w3.org/1999/xlink">c</sub> in magnetic fields of the BHO-doped VLS-YBCO was improved at various temperatures compared with a sample fabricated by the PLD method. However, discontinuous BHO nanorods were observed in the BHO-doped VLS-YBCO from TEM and EDX mapping.
