| 摘要 |
The invention relates to a force sensor having a layer sequence for determining a force acting on the layer sequence along a predefined force axis. The layer sequence includes, arranged successively in a vertical direction, a first magnetic layer with a first magnetization direction, a separating layer and a second magnetic layer with a second magnetization direction. Here, the first magnetization direction is secured with respect to the layer sequence. The second magnetic layer has a magnetostriction constant that is different from zero and a uniaxial magnetic anisotropy with an anisotropy axis. The uniaxial magnetic anisotropy is generated using shape anisotropy. The second magnetization direction encloses an angle of more than 0° and less than 90° with the force axis in the quiescent state, and the anisotropy axis encloses an angle of more than 0° and less than 90° with the force axis.
