Abstract
Multilayer magnetic transducer and structure and process for the production of the structure. The magnetic structure only has one stack of layers of a magnetic material separated by layers of a non-magnetic metallic material having a thickness such that there is an anti-ferromagnetic coupling between the magnetic layers, the magnetic material being chosen from among the alloys FeNi, FeNiCo, and NiCo and the non-magnetic material is silver.
