Abstract
- Given their excellent superconducting properties, REBa<subscript>2</subscript>Cu<subscript>3</subscript>O<subscript>y</subscript> (REBCO)-coated conductors (CCs) are anticipated to be utilized in a variety of magnet applications. To further increase the critical current density J <subscript>c</subscript> of these materials to levels needed for commercial applications, this study employs reel-to-reel (RTR) pulsed laser deposition (PLD) to fabricate REBCO+BaHfO<subscript>3</subscript> (BHO) CCs. PLD creates BHO nanorods, which serve as flux-pinning defects. The material is subjected to O<superscript>2+</superscript> irradiation to introduce more defects. The irradiation-induced defects serve as flux-pinning centers to the REBCO+BHO-nanorod CCs, increasing J <subscript>c</subscript> along the c axis and over a wide range of magnetic-field angles compared with conventional REBCO+BHO-nanorod CCs. Both nanorods and irradiation-induced defects are demonstrated to be effective pinning centers in this material. [ABSTRACT FROM AUTHOR]
