Abstract
According to one embodiment, a magnetic recording element includes a stacked body. The stacked body includes a first and a second stacked unit. The first stacked unit includes first and second ferromagnetic layers and a first nonmagnetic layer. The first nonmagnetic layer is provided between the first and second ferromagnetic layers. The second stacked unit is stacked with the first stacked unit and includes third and fourth ferromagnetic layers and a second nonmagnetic layer. The fourth ferromagnetic layer is stacked with the third ferromagnetic layer. The second nonmagnetic layer is provided between the third and fourth ferromagnetic layers. An outer edge of the fourth ferromagnetic layer includes a portion outside an outer edge of the first stacked unit in a plane. A magnetization direction of the second ferromagnetic layer is determined by causing a spin-polarized electron and a rotating magnetic field to act on the second ferromagnetic layer.
