A perpendicular magnetic tunnel junction may include a free layer, a reference layer, and a barrier layer. The barrier layer may be arranged between the free layer and the reference layer. The barrier layer may include a first interface and a second interface. The first interface may face the free layer, and a second interface may face the reference layer. The first interface may not physically correlate with the second interface.
