Abstract: The permanently growing requirements on computational processes urge the development of more and more powerful information technological devices. This ongoing progress can only be realized by pushing the limits of device sizes to continually smaller dimensions. Yet, the higher circuit densities consequently result in a rapidly increasing energy consumption in the respective applications. The generation of waste heat, mainly from Joule heating, represents a particularly large obstacle in this regard and prompts the search for more efficient methods of data processing and storage. The introduction of spintronics [1] marked a substantial advance in this field by combining conventional charge based electronics with the electron spin as an additional carrier of information. In particular, the generation, manipulation and detection of spin polarized currents constitute the basis for most spintronic effects and enable information transfer at lower charge current densities. However, despite this progress the power consumption still keeps rising and remains the most critical aspect in the development of modern information technology.
