Abstract

According to one embodiment, a magnetic memory device includes 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 perpendicular to a main surface thereof and corresponding to the first magnetization direction, a third magnetic layer provided between the first and second magnetic layers, having a fixed magnetization direction perpendicular to a main surface thereof and corresponding to the second magnetization direction, and having a side surface including a recess portion, and a nonmagnetic layer provided between the first and third magnetic layers.
