Prospective digital data storage devices predominantly rely on novel fundamental magnetic phenomena. The better we understand these phenomena, the better and more energy efficient the memory chips and hard drives we can build. Physicists from the Helmholtz-Zentrum Dresden-Rossendorf (HZDR) and the Helmholtz-Zentrum Berlin (HZB) have now completed the essential fundamental work for future storage devices: Using a creative approach of shaping magnetic thin films in curved architectures, they validated the presence of chiral responses in a commonly used magnetic material. This facilitates the creation of magnetic systems with desired properties that rely on simple geometrical transformations. The team has now presented their work in the journal Physical Review Letters.
