Abstract
A method of fabricating a superconductive flexible conductor having a high critical temperature in which method a deposit of superconductive ceramic is applied to a metal tape of thickness lying in the range 0.1 mm to 1 mm, wherein: PA0 the deposit of thickness lying in the range 50 .mu.m to 300 .mu.m and of concentration by volume of not less than 70% runs through an infrared beam at a speed of not less than 5 cm per minute, the zone treated by the the beam having a width of less than 10 mm relative to the travel direction and a surface temperature of not less than 1200.degree. C., thereby imparting a surface superconductive layer to the deposit which is of concentration by volume close to 100%, which is textured in the travel direction, and which is of thickness lying in the range 10 .mu.m to 100 .mu.m; and PA0 annealing is then performed under oxygen.
