摘要： A magnetoresistive sensor including: a first pinned-magnetization magnetic layer and a free-magnetization magnetic layer, separated by first separating layer for magnetic uncoupling. The sensor further includes a second pinned-magnetization magnetic layer, separated from the free-magnetization magnetic layer by a second separating layer for magnetic uncoupling, the first and second separating layers being located on either side of the free-magnetization magnetic layer, and the respective magnetizations of the first pinned-magnetization magnetic layer and of the free-magnetization magnetic layer, in the absence of an external field, are substantially orthogonal. The orientation of the magnetization of the second pinned layer is selectable.

摘要： The present invention relates to a magnetoresistive sensor comprising a first pinned-magnetization magnetic layer (410) and a second free-magnetization magnetic layer (430), called sensitive layer, separated by first separating layer (420) for magnetic uncoupling. The sensor further comprises a second pinned-magnetization magnetic layer (450), separated from said sensitive layer by a second separating layer (440) for magnetic uncoupling, the first and second separating layers being located on either side of said sensitive layer, and the respective magnetizations of the first pinned-magnetization magnetic layer and of the sensitive layer, in the absence of an external field, being substantially orthogonal. The orientation of the magnetization of the second pinned layer is selected.
