Abstract

A MLU cell for sensing an external magnetic field, including a magnetic tunnel junction including a sense layer having a sense magnetization adapted to be oriented by the external magnetic field; a reference layer having a reference magnetization; a tunnel barrier layer; a biasing layer having a biasing magnetization and a biasing antiferromagnetic layer pinning the biasing magnetization substantially parallel to the pinned reference magnetization at a low threshold temperature and freeing it at a high threshold temperature. A biasing coupling layer is between the sense layer and the basing layer and configured for magnetically coupling the biasing layer and the sense layer such that the sense magnetization is oriented substantially perpendicular to the pinned biasing magnetization and to the pinned reference magnetization. The present disclosure further concerns a magnetic sensor device for sensing an external magnetic field, including a plurality of the MLU cells.
