The method comprises: partially removing each of the stabilizer layers to expose a portion of the superconducting layer; bringing the exposed portions of the superconducting layers into contact with each other and fixing the superconducting layers to each other; heating the strands of superconducting wire to the melting point of the superconducting layers to melt-diffuse the superconducting layers in contact with each other and to join the strands of superconducting wire together; and oxidizing the junction between the strands of superconducting wire in an oxygen atmosphere (‘oxygenation annealing’). The oxygenation annealing restores the superconducting properties of the superconducting wires lost during the melting diffusion. According to the method, the superconducting layers are brought into direct contact with each other without any mediating material therebetween, followed by melting diffusion. Accordingly, the method enables the fabrication of sufficiently long superconducting wires without any substantial contact resistance, compared to non-superconducting joining. Particularly, the oxygen partial pressure is adjusted to a pressure close to a vacuum during the melting diffusion to lower the eutectic melting point of the superconductors, so that the superconducting wires can be joined together while protecting the constituent layers (e.g., the stabilizer layers containing silver (Ag)) from melting.08-19-2010
