Abstract
995710 Super-conductors INTERNATIONAL BUSINESS MACHINES CORPORATION 9 Sept 1963 [10 Sept 1962] 35464/63 Headings H1A AS and A4D A super-conductive composite electrical conductor is made by placing a metal superconductive at a given temperature in a sheath of metal which is not super-conducting at that temperature, reducing the cross-sectional area to form a unit conductor, grouping a plurality of units into a bundle and reducing the overall cross-section of the bundle. By repeated applications of this process filaments of super-conductor may be produced whose diameter is of the same order as the magnetic field penetration depth of the super-conductor. The diameter reduction may be achieved by swaging or drawing. In one embodiment the filaments are of lead and the sheath of aluminium. As the number of applications of the process increases, the resulting wire tends to take on super-conducting properties intermediate those of the two materials involved, e.g. a transition temperature of 3À4K was achieved, as compared with 7À2K for lead and 1À1K for aluminium. The method may therefore be used in the production of cryotron switching devices operating at specific temperatures. For producing a device having a high critical field, the electrons both of the filament material and the sheath material should have a small mean free path. In the ultimate limit the sheath material can be an insulator e.g. silver chloride. The filament material may be lead. In another such device the sheath may be an aluminium-zinc alloy and the filaments may be of a lead-bismuth alloy.
