Abstract
According to one embodiment, a magnetic memory element includes a memory layer, a first nonmagnetic layer, a reference layer, a second nonmagnetic layer, and an adjustment layer which are stacked. The adjustment layer is configured to reduce a leakage magnetic field from the reference layer. The adjustment layer is formed by stacking an interface layer provided on the second nonmagnetic layer, and a magnetic layer having magnetic anisotropy perpendicular to a film surface. Saturation magnetization of the interface layer is larger than that of the magnetic layer.
