ABSTRACT:
A magnetoresistive sensor for measuring the strength of a magnetic filed includes a stack of a reference element, a separation element and an element sensitive to the magnetic field. The reference element and the sensitive element have, respectively, a first and a second magnetic anisotropy in a first and a second direction. The sensitive element includes the superposition of a layer of a ferromagnetic material and a layer of an antiferromagnetic material which are arranged to obtain a magnetic moment having a component oriented in the direction of the field to be measured that varies reversibly in relation to the strength of the magnetic field to be measured, and linearly in an adjustable field range.
