Imagine storing a thousand times more information on your hard disk: Miniaturization of devices is an important goal in contemporary science and technology. Data storage devices form the cornerstone of the technologically advanced world that we live in. In current data storage devices information is currently stored at the macroscopic level, but the ultimate aim is to be able to store information in individual molecules. So far this vision has remained beyond the reach of scientists. The groups led by Professors Sarkar (FU Berlin), Van Slageren (Universität Stuttgart) and Prof. Neese and Prof. Atanasov (MPI for Chemical Energy Conversion, Mülheim an der Ruhr) have now achieved a major breakthrough by developing the first single-transition metal ion complex with stable magnetization, which they have published in the high-ranking interdisciplinary journal Nature Communications.
