Hidden Harmonies: Team discovers Magnon-phonon Fermi resonance in an antiferromagnet - Helmholtz-Zentrum Dresden-Rossendorf, HZDR

A bottleneck of nowadays data processing technology is the slow and energy-consuming data storage. Soon, data storage centers are expected to consume almost 10 percent of the world’s energy generation. This increase is, among other things, due to intrinsic limitations of the materials used – ferromagnets. Consequently, this problem has ignited a quest for faster and more energy efficient materials. One of the most encouraging pathways are antiferromagnets – materials that not only promise more robust and 1.000 times faster read and write operations but also are more abundant than their ferromagnetic counterparts. Understanding and control of these quantum materials is key to advancing future technologies. An international research team now reports on a major step forward in this endeavor, as the scientists report in the journal Nature Communications (DOI: https://doi.org/10.1038/s41467-024-49716-w).
