Abstract: We have studied a hot-wall heating system to produce GdBa2Cu3O y (GdBCO) films with large critical currents (I c) at a high production rate by a pulsed-laser-deposition (PLD) method. GdBCO films fabricated at a production rate of 30m/h under the optimized conditions, especially a distance of 95mm between the target and the substrate (T–S), exhibited high critical current densities (J c) of about 3MA/cm2 and I c over 300A at a thickness of 1–2μm. Furthermore, long GdBCO tapes prepared by repeated depositions at each tape-passing speed of 80m/h showed uniform I c distribution along the longitudinal direction, because the hot-wall system enabled to stabilize temperature within a few degrees at 800°C. A 170m long tape with I c over 600A was successfully fabricated at a production rate of 16m/h using a laser power of 360W. [ABSTRACT FROM AUTHOR] |
