Electrically controlled exchange bias
(EB) denotes a magnetic coupling phenomenon at ferromagnetic (FM)/antiferromagnetic (AF) interfaces with strong implications in modern spintronics. It manifests most strikingly in a shift of the FM hysteresis along the magnetic field axis. Although the theoretical details of this unidirectional anisotropy are still unclear, it turns out, that a net AF interface magnetization is essential for the EB and allows for extrinsic control of the effect.

Predicting universal properties of complex systems requires information about the spatial dimensionality and symmetry of the interaction. Magnetic model systems provide access to these parameters. We use an experimental approach in order to study fundamental aspects of statistical physics with the help of magnetic model systems.
