Publication number: 20230243897Abstract: The techniques described are applicable to closed-loop magnetic multi-turn sensors including giant magnetoresistance (GMR-MT) sensors as well as tunnel magnetoresistive (TMR) multi-turn sensors. Techniques, e.g., lithography techniques, are described to form crossings so that a distortion of an ideal shape is reduced or minimized. Another aspect describes techniques to modify the material thickness and/or magnetic properties in such an area of the crossing. Yet another aspect describes techniques to locally weaken the applied field in the area of the crossing to prevent nucleation events in this area. The techniques described are applicable to closed-loop magnetic multi-turn sensors including giant magnetoresistance (GMR-MT) sensors as well as tunnel magnetoresistive (TMR) multi-turn sensors.Type: ApplicationFiled: January 20, 2023Publication date: August 3, 2023Inventors: Jan Kubik, Jochen Schmitt, Onur Necdet Urs

Publication number: 20210372820Abstract: A giant magnetoresistance (GMR) element is provided for use in a magnetic multi-turn sensor in which the free layer, that is, the layer that changes its magnetization direction in response to an external magnetic field so as to provide a resistance change, is thick enough to provide good shape anisotropy without exhibiting an AMR effect. To achieve this, at least a portion of the free layer comprises a plurality of layers of at least two different materials, specifically, a plurality of layers of at least a first material that is ferromagnetic and a plurality of layers of at least a second material that is known not to exhibit an AMR effect and that does not interfere with the GMR effect of the layers of ferromagnetic material.Type: ApplicationFiled: May 11, 2021Publication date: December 2, 2021Inventors: Jochen Schmitt, Cian Padraic O Dalaigh, Md Tarequzzaman, Onur Necdet Urs, Jan Kubik, Enno Lage
