The third magnetic layer has at least one crystal structure selected from the group consisting of a face-centered cubic crystal structure and a face-centered tetragonal crystal structure and is (111) oriented parallel to a film plane of the third magnetic layer. According to this production method, it is possible to produce a magnetoresistive element with excellent properties and thermal stability.

摘要： A magnetic control device including an antiferromagnetic layer, a magnetic layer placed in contact with one side of the antiferromagnetic layer, and an electrode placed in contact with another side of the antiferromagnetic layer, wherein the direction of the magnetization of the magnetic layer is controlled by voltage applied between the magnetic layer and the electrode. In particular, when an additional magnetic layer is further laminated on the magnetic layer placed in contact with the antiferromagnetic layer via a non-magnetic layer, the direction of the magnetization of the controlled magnetic layer can be detected as a change in the electric resistance. Since such a magnetic control device, in principle, responds to the electric field or magnetic field, it forms a magnetic component capable of detecting an electric signal or a magnetic signal. In this case, the direction of the magnetization basically is maintained until the next signal is detected, so that such a device also can form an apparatus. Thus, a magnetic control device capable of controlling the magnetization with voltage and magnetic component and a memory apparatus using the same are provided.
