The Takeaway
Ultrathin magnetic membranes exhibit a coupling between magnetic waves and physical vibrations that far exceeds what is possible in bulk materials. This interaction, known as magnomechanical coupling, is usually so faint that it requires extreme precision to detect. By using two-dimensional van der Waals magnets, researchers have unlocked a level of efficiency that was previously unthinkable. This massive boost enables a new class of ultra-fast quantum processors that use mechanical vibrations to store and move magnetic data. It paves the way for information technology that is both smaller and significantly more energy-efficient than current silicon chips.
From the abstract
Magnomechanical systems provide a promising route for exploring coherent hybrid magnon-phonon interactions and hybrid information processing, but their realization has so far been limited by weak magnon-phonon coupling in conventional bulk platforms. We show that a suspended membrane of a two-dimensional van der Waals ferromagnet with in-plane magnetization and out-of-plane mechanical oscillations exhibits large magnomechanical coupling dominated by magnetoelastic interactions. The parametric si
