This article discusses a study by researchers from the University of Vienna and other institutions, exploring the use of alternating currents to excite spin waves in magnetic materials for more energy-efficient computing. The study highlights the potential of magnons, quanta of spin waves, for alternative computing architectures, addressing the limitations of traditional CMOS-based processors. By generating and steering spin waves efficiently through ferrimagnetic vortex pairs, the researchers demonstrate a promising path toward reprogrammable magnonic circuits, offering an innovative solution for miniaturization and energy-saving in computing systems.
