The material is switched to anothre structure by applying surface strain, imposed by the substrate layer.
The material is switched to anothre structure by applying surface strain, imposed by the substrate layer. It is an important step forward in spintronics: the magnetic state of certain materials can be switched using surface induced strain. All our electronics are based on electrical charges being transported from one place to another. Electrons move, current flows, signals are transmitted by applying an electrical voltage. However, there is also another way to manipulate electronic currents and signals: using the properties of the spin - the intrinsic magnetic moment of the electron. This is called "spintronics", and it has become an increasingly important field in contemporary electronic research. An international research team involving TU Wien and the Czech Academy of Sciences has now achieved an important breakthrough: they have managed to switch the spins in an antiferromagnetic material using surface strain.
