Abstract

A magnetic memory device may include a first ferromagnetic layer, a second ferromagnetic layer, and a tunnel barrier layer arranged on a substrate. The tunnel barrier layer may include a crystal structure and may be arranged between the first ferromagnetic layer and the second ferromagnetic layer. At least the first ferromagnetic layer may include a first layer in contact with the tunnel barrier layer and a second layer in contact with the first layer, and an orientation of the first layer with respect to the tunnel barrier layer may be greater than an orientation of the second layer with respect to the tunnel barrier layer.
