Meyer, G

A method for producing electrical super-conductors consisting of a great number of mutually spaced thin filaments of a super-conductive material in which diffusion is effected in mutually spaced zones between two adjoining metallic layers, one being vanadium and the other a copper-gallium alloy by establishing similar mutually spaced zones in the layers in which the diffusion is either prevented or the superconductive properties of the inter-metallic compound formed by the diffusion is the superconductive properties of the inter-metallic compound formed by the diffusion is considerably reduced. In one mode of the method, mutually spaced zones of non-diffusion in the layers are established by use of mutually spaced zones of molybdenum or tantalum between the layers which prevent interdiffusion therebetween from taking place. In another mode of the method, mutually spaced zones of diminished super-conductive properties are established by use of mutually spaced zones of tin or aluminum which are caused to be diffused into the vanadium layer. 13 claims, 2 figures.
