  • Magnetic tunnel junction device and method for manufacturing the same
    Patent number: 8329478
    Abstract: The present invention relates to a magnetic tunnel junction device and a manufacturing method thereof. The magnetic tunnel junction device includes i) a first magnetic layer having an switchable magnetization direction, ii) a nonmagnetic layer provided on the first magnetic layer, iii) a second magnetic layer provided on the nonmagnetic layer and having a fixed magnetization direction, iv) an oxidation-preventing layer provided on the second magnetic layer, v) a third magnetic layer provided on the oxidation-preventing layer and fixing the magnetization direction of the second magnetic layer through magnetic coupling with the second magnetic layer, and vi) an antiferromagnetic layer provided on the third magnetic layer and fixing a magnetization direction of the third magnetic layer.
