Structures of transducers magnetic a thin films, biased by coupling exchange

摘要

P structures of the magnetic transducers with thin films. In a magnetic transducer to thin films, of the magnetoresistive or inductive type, a layer of ferromagnetic material 31 and an antiferromagnetic material layer 33 are deposited on one another and coupled by heat exchange to have a unidirectional polarization he in the plane of the ferromagnetic material. When use is made of a plurality of pairs of such layers, these pairs are separated by layers made of non-magnetic material. / p & & p & structures which can be used in particular in the magnetic heads for transduction of digital data. / p
