Abstract
A magnetic sensor device for sensing an external magnetic field includes a plurality of MLU cells, each MLU cell having a magnetic tunnel junction including a sense layer having a sense magnetization freely orientable in the external magnetic field, a storage layer having a storage magnetization; and a tunnel barrier layer between the sense layer and the storage layer. The magnetic sensor device includes a stress inducing device configured for applying an anisotropic mechanical stress on the magnetic tunnel junction such as to induce a stress-induced magnetic anisotropy on at least one of the sense layer and the storage layer. The stress-induced magnetic anisotropy induced by the stress inducing device corresponds substantially to a net magnetic anisotropy of the at least one of the sense layer and the storage layer. The magnetic sensor device can be programmed easily and has improved sensitivity.
