Abstract
A magnetic sensor element is disclosed, comprising a magnetic tunnel junction (MTJ) comprising a reference layer, a tunnel barrier layer, a sense layer having a sense magnetization freely orientable in the presence of the external magnetic field. The reference layer has a reference magnetization and comprises a reference SAF structure and an in-plane sensitivity axis. A SOT electrode configured to pass a SOT current adapted to switch the first reference magnetization in two opposed directions along the sensitivity axis by a spin orbit torque interaction. Also disclosed is a sensing device comprising at least one sensing branch including at least one magnetic sensor element and a sensing operation using the sensing device for sensing an external magnetic field. The magnetic sensor element allows for sensing the external magnetic field with low 1/f noise.
