According to one embodiment, a nano-imprint mold includes plural pairs of first and second protrusions formed on a base layer, each of which is formed along the same straight line. Each protrusion has a top surface and four side surfaces. The first and second protrusions are mirror-symmetrical with each other. A first side surface of the first protrusion and a second side surface of the second protrusion face each other. A first angle between the first side surface or the second side surface and a main surface of the base layer is not less than 85° and not more than 90°. A second angle between a third side surface in the first protrusion or a fourth side surface in the second protrusion and the main surface of the base layer is not less than 70° and not more than 88°. The first angle is larger than the second angle.

According to one embodiment, a magnetic memory element includes a stacked body including first and second stacked units stacked with each other. The first stacked unit includes first and second ferromagnetic layers and a first nonmagnetic layer provided therebetween. The second stacked unit includes third and fourth ferromagnetic layers and a second nonmagnetic layer provided therebetween. Magnetization of the second and third ferromagnetic layers are variable. Magnetizations of the first and fourth ferromagnetic layers are fixed in a direction perpendicular to the layer surfaces. A cross-sectional area of the third ferromagnetic layer is smaller than a cross-sectional area of the first stacked unit when cut along a plane perpendicular to the stacking direction.
