1. A method for generating closed flux magnetization patterns of predetermined rotational directions in a magnetic reference layer and a pinned layer of a magnetic layer stack, the method comprising:
applying an external magnetic field in a predetermined direction to the magnetic layer stack causing magnetic saturation of the magnetic reference layer and of the pinned layer of the magnetic layer stack; and
reducing the external magnetic field to form a first closed flux magnetization pattern in the magnetic reference layer and a second closed flux magnetization pattern in the pinned layer.
