Discovery of magnon–phonon resonance could revolutionize data storage

An international research team has discovered magnon–phonon Fermi resonance in the antiferromagnetic material cobalt difluoride (CoF2), enabling energy transfer between these quasiparticles. This advancement could lead to data storage technologies that are 1,000 times faster and more energy-efficient than current ferromagnetic materials. The study, published in *Nature Communications*, highlights the potential for enhanced spin-lattice coupling and reduced energy consumption in data writing operations.
