Storing more and more in an ever-smaller space – what sounds impossible is in fact just part of the daily routine in information technology, where for decades, increasing amounts of data have been successfully stored on media with ever higher densities. An international team, including researchers from Forschungszentrum Jülich, has now discovered a physical phenomenon that could prove suitable for use in further data aggregation. They found that domain walls, which separate areas in certain crystalline materials, display a polarization, potentially allowing information to be stored in the tiniest of spaces, thus saving energy. The results of this study have been published in the latest edition of the journal Nature Communications.
