Patent ID: 7898833

Claim:
A magnetic element with thermally-assisted writing using a field or spin transfer, each comprising: a magnetic reference layer referred to as the “trapped layer”, the magnetization of which is in a fixed direction; a magnetic storage layer called the “free layer” having a variable magnetization direction and consisting of a layer made of a ferromagnetic material with magnetization in the plane of the layer and magnetically coupled to a magnetization-trapping layer made of an antiferromagnetic material; and a semiconductor or an insulating layer with confined-current-paths sandwiched between the reference layer and the storage layer; wherein at least one bilayer consisting respectively of an amorphous or quasi-amorphous material and a material having the same structure or the same crystal lattice as the antiferromagnetic layer is present in the storage layer between the ferromagnetic layer, which is in contact with the semiconductor or insulating layer with confined-current-paths, and the antiferromagnetic layer.
