Abstract
Disclosed is a magnetic tunnel junction device whose fixed layer has a simplified structure and in which the number of stacked layers is reduced. The magnetic tunnel junction device comprises a free layer whose magnetization direction is variable, a fixed layer whose magnetization direction is fixed and that is formed as a single layer, and a dielectric layer stacked between the free layer and the fixed layer. One or more of the free layer and the fixed layer are an L1type magnetic alloy layer, and the dielectric layer has a (111) texture.
