Abstract
A magnetic memory device including a first magnetic layer selectively exhibiting a first state in which the first magnetic layer has a first magnetization direction perpendicular to a main surface thereof and a second state in which the first magnetic layer has a second magnetization direction opposite to the first magnetization direction; a second magnetic layer having a fixed magnetization direction which is perpendicular to a main surface thereof and which corresponds to the first magnetization direction, and having a top surface including a recess portion or a bottom surface including a recess portion; a third magnetic layer provided between the first magnetic layer and the second magnetic layer, and having a fixed magnetization direction which is perpendicular to a main surface thereof and which corresponds to the second magnetization direction; and a nonmagnetic layer provided between the first magnetic layer and the third magnetic layer.
