Abstract
A magnetic detector which includes a first thin-layer element and a second thin-layer element made of magnetic material with magnetic anisotropy in the plane possessing, in this plane, two easy axes of magnetization. A coercive field of one of the first and second thin-layer elements has a value different from that of the other thin-layer element. The two thin-layer elements have elongated and mutually parallel shapes perpendicular to their direction of easy magnetization in the absence of a magnetic field. The width of these thin-layer elements is such that it obliges at least one of the thin-layer elements to have its magnetization oriented along the length of the thin-layer element when there is no external magnetic field. Such a magnetic field sensor may find particular application to the measurement of magnetic fields.
