Abstract
According to one embodiment, a magnetic memory device includes: a first magnetic layer; a nonmagnetic layer on the first magnetic layer; a second magnetic layer on the nonmagnetic layer; and an insulator film on the nonmagnetic layer surrounding a side surface of the second magnetic layer. The second magnetic layer has an area of a surface facing the nonmagnetic layer smaller than that of the nonmagnetic layer. The nonmagnetic layer includes a first region that is provided between the first magnetic layer and the insulator film. The first region includes an amorphous state.
