ABSTRACT:
A magnetic field sensor structure including a first magnetoresistive element in a spin-valve arrangement with a first reference layer structure with a first reference magnetization direction and a second magnetoresistive element in a spin-valve arrangement with a second reference layer structure with a second reference magnetization direction, wherein the first and second magnetoresistive elements are arranged in a layer vertically above each other and galvanically isolated from each other by an intermediate layer, and wherein the first and second reference magnetization directions are different.
