Abstract
A magnetic sensor system includes a magnetoresistive sensor comprising a magnetic free layer having a sensing plane and a magnetically-free magnetization arranged within the sensing plane, where the magnetically-free magnetization is variable in a presence of an in-plane magnetic field that is aligned with the sensing plane; and a ferromagnetic disc having a magnetic vortex in a ground state, wherein the magnetic vortex is configured to react to an out-of-plane magnetic field and generate a stray field in response to the out-of-plane magnetic field being applied to the ferromagnetic disc. The stray field has an in-plane magnetic field component that is proportional to the out-of-plane magnetic field. The magnetic free layer is configured to receive the in-plane magnetic field component of the stray field. The magnetically-free magnetization is configured to change based on the in-plane magnetic field component of the stray field.
