Abstract

We achieved a very low resistance at 0.02 ∼ 0.03 νΩ (12 nΩcm²) across the nonsuperconducting joint with an area of 2 × 20 mm² for YBCO coated conductors produced by pulsed laser deposition (PLD). The joint technique was very simple in which YBCO coated conductors were stuck in a face to face manner with Ag surfaces in contact and heat-treated at 500°C in an oxygen atmosphere. We also confirmed that the good superconducting properties of the YBCO coated conductors were maintained after completion of the series of joint procedures. Furthermore, a low contact resistance of 0.5 nΩcm² at the interface between the YBCO film and the Ag stabilizing layer was confirmed.
