摘要:
The disclosed magnetic tunnel junction (3) includes a synthetic antiferromagnetic free layer structure (30) comprising a magnetic core (32) and a magnetic shell (31), the magnetic core comprising a magnetic layer (321) having an aspect ratio between 0.5 and 2, the magnetic shell surrounding the magnetic core at least partly along its thickness, and the magnetization of the magnetic shell being antiferromagnetically coupled with the magnetization of the magnetic core. A corresponding fabrication method is disclosed as well.
