ABSTRACT:
It is possible to perform a writing operation with low power consumption and a low current, and enhance reliability without causing element breakdown. There are provided a first magnetization-pinned layer including at least one magnetic film in which a magnetization direction is pinned; a second magnetization-pinned layer including at least one magnetic film in which a magnetization direction is pinned; a magnetic recording layer formed between the first magnetization-pinned layer and the second magnetization-pinned layer and including at least one magnetic film in which a magnetization direction is changeable by injecting spin-polarized electrons; a tunnel barrier layer formed between the first magnetization-pinned layer and the magnetic recording layer; and a nonmagnetic intermediate layer formed between the magnetic recording layer and the second magnetization-pinned layer. The magnetization direction of the magnetic film of the first magnetization-pinned layer on the magnetic recording layer side is substantially anti-parallel to the magnetization direction of the magnetic film of the second magnetization-pinned layer on the magnetic recording layer side.
