Abstract
A magnetic field sensor apparatus is provided for measuring one magnetic field vector component H. The apparatus includes at least one anisotropic magneto-resistive resistor device (AMR resistor device) on a chip substrate, where the resistor device includes a plurality of magneto-resistive AMR resistor elements which are connected in series by electrically conductive strips. At least one permanent-magnetic magnetization element with a magnetization axis is assigned to each resistor element in such a way that the resistor element is passed through by an initial magnetization field Hof the magnetization element in the direction of the magnetization axis. A measurement current Iflowing through the resistor element from a contact region between a first conductive strip and the resistor element to a contact region between the resistor element and a second conductive strip has a mean current direction axis at a predefined linearization angle α>0° and α<90° relative to the magnetization axis. A highly sensitive magnetic field sensor apparatus can be manufactured economically in large numbers.
