Abstract
A method for preparing a structure having enhanced magneto-resistance, and use of the structure, in which it is possible to prepare a structure having enhanced magnetoresistance on the basis of the system of materials Cu--Co, especially for a magnetoresistive sensor. An intermediate of the structure is formed initially from an alloy having Cu mixed crystals supersaturated with Co by means of a rapid-solidification technique and this intermediate is subsequently converted by means of a predefined heat treatment into an end product of the desired structure having precipitations of or including Co in a Cu matrix.
