Abstract
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.
