Influence of Deposition Temperature on Critical Current Properties for Nd:YAG-PLD-YBa2Cu3Oy Thin Films with Nanorods
Abstract Bi-axially oriented YBCO thin films with BNO-nanorods were obtained by a low cost PLD process using Nd:YAG-laser in the substrate temperature ( T s) range of 850-890iC, and the degrees of orientation for the films are comparable to those of YBCO films prepared by PLD with excimer-laser. The vortex-Bose-glass-like behavior of irreversibility lines emerged and strongly depended on T s in the YBCO films with BNO-nanorods. Dependence of J c on the magnetic field was improved by introduction of BNO-nanorods, whereas J c properties were sensitively affected by T s. Control of T s is an important factor for the production of high-performance REBCO coated conductors with nanorods.
