    摘要: This magnetic writing element, writing by thermally-assisted spin field or transfer, comprises: a reference magnetic layer, called the "trapped layer", the magnetization of which is of fixed direction; a storage magnetic layer (40) called the "free layer", the magnetization direction of which is variable, and formed from a layer (47) made of a ferromagnetic material magnetized in the plane of the layer, and magnetically coupled to a trapping layer (41) made of an antiferromagnetic material; and an insulating or semiconducting or confined-current-path layer (42) interposed between the reference layer and the storage layer. One or more by-layers are interposed within the storage layer, between the ferromagnetic layer (47) in contact with the insulating or semiconducting or confined-current-path layer (42) and the antiferromagnetic layer (41), said by-layers being formed from an amorphous or quasi-amorphous material (45) and from a material (46) having the same structure or the same crystallographic lattice as the antiferromagnetic layer respectively.
